«Control and Optimization of Distributed Generation Systems»

Abstract: The existing electricity grid has small number of producers, long distribution ways and high maintenance cost. It is also difficult to achieve load balancing. Moreover, the depleting fossil fuels and the adverse effect on environment by its consumption has gain multi-national interest in reducing the excess use of nonrenewable energy resources and many nations are keeping tap on Co2 emissions.
The main concerns with the existing centralized power system grid have led to Increasing demand and lack of high reliability and security threats with power quality, to name a few.
This in turn urges the need to incorporate distributed generating (DG) units into the existing power systems consumers. DG units are the emerging micro-generating technologies such as micro-turbines, fuel cells, Internal Combustion (IC) engines. It also make use of renewable energy sources such as Photo Voltaic (PV) arrays and wind turbines. The DG units have low emission rates, environment friendly and are economical. The introduction of DG units should reduce the pressure on central power grid principally but in technically speaking, penetration of distributed generation into the power grid creates a new class of issues different from those found in traditional power sources.

In this presentation, motivation towards development of DG and an overview will be presented on the two key aspects, modeling and control, of DG. Recent developments in these two key aspects will be presented. A better control strategy, by viewing DG as a special case of system of systems (SoS), will be discussed.

«Stabilization of Time-Varying and Nonlinear Systems with Pointwise and Distributed Delays Through the Reduction Model Approach»

Abstract: The reduction model approach is a well-known stabilization technique for systemswith input delays. It is effective for stabilizing continuous-time linear time-invariant systems with arbitrarily long pointwise or distributed input time-invariant delays. Recent extensions of this technique have been developed. We will present three extensions: we will show how (i) several families of time-varying systems can be handled (ii) local stabilization results for nonlinear systems with estimates of the basins of attraction (iii) the sampled control can be used when a limitation on the size of the sampling interval is imposed. Lyapunov-Krasovskii functionals are key tools of the proofs of our results.

«From Challenges to Control Solutions in Underwater Robotics: Beyond the Lab Experiments »

Abstract: Underwater vehicles have gained an increased interest in the last decades given the multiple tasks they can accomplish in various fields such as dams’ inspection, oil and gas industry, and environmental investigations. One of the potential applications of these systems deals with underwater inspection of facilities such as bridges, hydraulic dams, boat hulls, aquatic environments, etc. When we are interested in autonomous control of Remotely Operated Vehicles (ROVs), different challenges may arise. These challenges are mainly due to the inherent high nonlinearities and time varying behavior of the vehicle’s dynamics subject to hydrodynamic effects and external disturbances.
In order to avoid the degradation in the performance of the controlled system during a specific mission, the vehicle is expected to possess a self tuning ability and robustness to compensate for different kinds of uncertainties, parameters variation and external disturbances. That is why adaptive and robust controllers are very popular for such systems.
The heart of this talk is organized in four main parts. The first one deals with an overview of the context of underwater inspection and its related control problems and challenges. The second part introduces our three underwater vehicles, namely the AC-ROV, the LIRMIA2 and the L2ROV.  In the third part, the proposed adaptive and robust control solutions will be presented as well as their real-time implementation on the above underwater vehicles. The obtained results are illustrated through different experimental results in different conditions in a swimming pool environment. The last part shows the application of some of the proposed control strategies in challenging real operating conditions in the Mediterranean sea.

Abstract: Rapid increase in the use of wireless services over the last two decades has lead the problem of the radio-frequency (RF) spectrum exhaustion. More specifically, due to this RF spectrum scarcity, additional RF bandwidth allocation, as utilized in the recent past, is not anymore a viable solution to fulfill the demand for more wireless applications and higher data rates. Among the many proposed solutions, optical wireless communication (OWC) systems have gained an increasing interest due to their advantages including higher bandwidth and higher capacity compared to the traditional RF communication systems. This promising technology offers full-duplex Gigabit throughput in certain applications and environment while benefiting from a huge license-free spectrum, immunity to interference, and high security. These features of OWC communication systems potentially enable solving the issues that the RF communication systems face due to the expensive and scarce RF spectrum. The first part of the talk will give an overview of OWC systems by offering examples of advantages and application areas of this emerging technology. In the second part of talk, we will focus on some recent results and on-going research directions in the accurate characterization of the performance of OWC systems in the presence of inevitable impairments due to atmospheric turbulence and misalignment between transmitter and receiver.

Keywords/Mots-clefs: Optical wireless communication, free space optical communication, atmospheric turbulence, pointing error, Gamma-Gamma fading, Lognormal fading, and capacity and error rate computation.

«POPS-OFDM: Ping-pong Optimized Pulse Shaping OFDM for 5G Cellular Systems and Beyond»

Abstract: Next generation mobile communication systems will face stringent propagation conditions ranging from large Doppler spreads in frequency to excessive multipath spreads in time, both of which can be of natural or artificial origins. First of all, natural severe Doppler dispersions are to be experienced in next generation mobile communications because of expected high speed mobility as well as the use of new frequency bands beyond those used today. Secondly, slower loops for time advance and frequency control, needed to alleviate the synchronization overhead burden for very small packet communications, needed in low latency applications of tactile internet, will incur severe synchronization errors especially in the time domain. Last but not least, the use of the CoMP (Coordinated Multi-Point) technique, in its JP (Joint Processing) version, and the MBMS (Multimedia Broadcast Multicast Service) services in LTE, and its SFN (Single Frequency Network) counterpart in DVB-T, will cause severe artificial time dispersions that cannot be tackled by today cyclic prefix OFDM systems.
Unfortunately, conventional OFDM with CP (Cyclic Prefix) can no longer cope with these severe and challenging impairments, which will for sure be faced by 5G systems and beyond. The proposed solution, subject of the keynote speech, is to have recourse to pulse shaped (PS) OFDM. The idea behind PS-OFDM is to use non-perfectly orthogonal waveforms, unlike those of conventional OFDM, which can however better stand against time and frequency channel distortions.
After presenting an overview of conventional OFDM with guard interval insertion, with both its PC and ZP (Zero Padding) versions, and OFDM/OQAM, we present a new paradigm for simple and systematic pulse shape optimization for any given channel impairments: POPS-OFDM (Ping-pong Optimized Pulse Shaping OFDM). We show how the new waveforms can withstand these impairments, how we benefit from an increased robustness to unexpected time and frequency synchronization errors, and how we can dramatically reduce out of band spurious emissions for a peaceful coexistence of adjacent frequency and power uncoordinated transmissions.
We finish the keynote speech by presenting several perspectives for pulse shaping, pertaining to partially equalized OFDM, multi-pulse OFDM and single- and multi-pulse OFDM/OQAM.

«Possibilistic Scene Interpretation»

Abstract: Scene interpretation is defined as the process, based on expert's fixed goals, and allowing the automatic extraction of meaningful semantic information content by the application of image analysis and image understanding approaches as well as the use knowledge representation and reasoning techniques. Several approaches ofscene interpretation have been proposed. Most of these approaches use hierarchical interpretation strategy using different semantic levels of detail. Two major scene interpretation strategies are already proposed: Image-driven and model-driven scene interpretation strategies. In image-driven scene interpretation, also referred to as bottom-up strategy, processing proceeds from digital images to features components extraction (partitioning the observed image into meaningful features such as segments, lines, regions, objects…) to features description and characterization, and finally to features recognition (assigning semantic labels to each feature component based on its intrinsic attributes or its context vis-à-vis its neighboring features). On the other hand, model-driven, or top-down strategy, consists on the use of a set of assumptions/properties/models of expected scene contents, i.e. feature components such as regions, objects….. The properties of these feature components are tested against a set of feature component prior models, or representations, of ever decreasing levels of abstraction. Through a series of test/validate processes, one eventually reaches an interpretation at the parent image semantic level.
Major difficulties in scene interpretation are related to: the knowledge representation of different elements constituting the scene (pixels, regions and objects) as well as the relationships between these elements; the interpretation strategy; and, the management of different forms of information imperfections related to the used data, sensors as well as the knowledge injected by the experts.
Main challenges in the field of scene interpretation are:

1) Knowledge representation, i.e. how to model prior knowledge about possible scene description?

2) Hypotheses matching, i.e. how to match possible scene descriptions against incomplete and erroneous detections of objects in an image?

3) Inference, i.e. how to derive inferences from prior knowledge in order to improve and complete the scene description?
Two types of knowledge can be exploited in scene interpretation approaches:

  • Descriptive knowledge related to the used sensors as well as the expert's knowledge. This knowledge may be given/expressed through different forms (symbolic or numeric), and may suffer from different forms of imperfection (uncertainty, ambiguity, missing data, reliability….);
  • Operational knowledge related to the proposed methods and algorithms allowing to extract meaningful information from the observed image analyzing;

It is worthwhile to notice that human knowledge is generally expressed using epistemic terms not only because they are the most common form for the representation of human knowledge but because our knowledge about many aspects is ambiguous. Keeping this observation in mind, the presented research work proposes a possibilistic-based scene interpretation approach that can embrace human-like intelligence in image understanding and scene interpretation as we humans do.
This presentation is organized as follows. After the presentation of the scene interpretation concepts, a brief introduction to the possibility theory is given. The application of possibilistic knowledge representation and reasoning mechanisms into the major scene semantic levels (i.e. sub-pixel, pixel, region, object and global scene) is detailed using two real-world scene cases: environmental scene observed using multispectral remote sensing imaging, and a medical scene concerning mammographic median imaging. Results and research openings are detailed and discussed.

«Technologies and Applications of Photovoltaic Solar Cell»

Abstract: There are four main types of renewable energies; solar energy, wind energy, hydro and geothermal energy and biomass energy. Solar energy, in one form or another is the source of nearly all energy on the earth. Photovoltaics (PV) are a simple, practical and elegant method of harnessing the sun's energy.  PV devices (solar cells) are unique in that they directly convert the incident solar radiation into electrical power, with no noise, pollution or moving parts, making them robust, reliable and long lasting. Solar cells are based on the same principles and materials behind the communications and computer revolutions. This presentation covers the operation, use and applications of photovoltaic devices and systems. Mainly there are two types of photovoltaic devices; crystalline silicon (monocrystalline and polycrystalline) and thin-film solar cell devices.
 Unlike monocrystalline-based solar panels, polycrystalline solar panels do not require the Czochralski process. Raw silicon is melted and poured into a square mold, which is cooled and cut into perfectly square wafers. The process used to make polycrystalline silicon is simpler and cheaper. The amount of waste silicon is less compared to monocrystalline. On the other hand the efficiency of polycrystalline-based solar panels (typically 13-16%) is lower than monocrystalline because of lower silicon purity.  It is generally needed to cover a larger surface to output the same electrical power as compared with a solar panel made of monocrystalline silicon.
Depositing one or several thin layers of photovoltaic material onto a substrate is the basic gist of how thin-film solar cells are manufactured. The different types of thin-film solar cells can be categorized by which photovoltaic material is deposited onto the substrate, namely: Amorphous silicon (a-Si), Cadmium telluride (CdTe), Copper indium gallium selenide (CIS/CIGS) and Organic photovoltaic cells (OPC). Depending on the technology, thin-film module prototypes have reached efficiencies between 7–13% and production modules can operate at about 9%. Future module efficiencies are expected to climb close to the about 10–16%. The advantage of thin film solar cells that mass-production is simple. This makes them potentially cheaper to manufacture than crystalline-based solar cells. Also high temperatures and shading have less impact on solar panel performance. The main disadvantages of these systems although they are cheap, but they also require a lot of space as compared with crystalline devices.  Also thin-film solar panels tend to degrade faster than mono- and polycrystalline solar panels, which is why they typically come with a shorter warranty.

«Monitoring of land degradation from space : An integrated approach of remote sensing and in-situ measurements»

Abstract: Soil degradation limits plant growth, reduces crop productivity and degrades soil. We conducted a remote sensing analysis to discern features and patterns of degraded soils. Hyper- and multi-spectral data are used within different spatial and spectral resolution. 
A remote sensing classification of the degraded soilsand Land use was made using Maximum likelihood, Support Vector Machine, and Minimum Distance.
Computed accuracy from the classification varied between 46% and 75%.  Support Vector Machine gave the best results in extracting the patterns and features of eroded and saline soil classes (kappa coefficient of 63% and overall accuracy of 75%).
To generate a predicted salinity map, a multiple linear regression, based on the best-correlated indices is conducted. Spectral indices were also used to characterize degraded soils. The Linear Spectral Unmixing technique (LSU) is applied in this research work to improve the prediction models of degraded soils.
The developed remote sensing models enable us to highlight areas in immediate need of conservation strategies and control further soil degradation.

Mohamed SialaBiography: After the completion of an Engineering degree (2005) in Water and Soil Management and then a Master degree in Environmental engineering and management, I worked in the private sector. Between 2006 and 2007 I was involved in environmental impact studies by using Remote sensing and GIS techniques in a Tunisian-Italian company for environmental engineering. In my term as Engineer I had the opportunity to participate in several projects in land and water management for rural regions in northern Tunisia.
From 2008, I went on to pursue a PhD within the Remote Sensing Group at the Technical University of Freiberg in Germany. The focus of my doctoral thesis was the monitoring of land degradation in Ethiopia, Tunisia and Brazil using remote sensing and GIS advanced techniques. This work resulted in several publications in international journals and I presented it at major geoscience conferences. Throughout my academic research from undergraduate to doctoral level I have specialized in developing models to study land degradation and interactions with land use, vegetation cover, and climatic parameters. After my PhD thesis, I received anAlexander von Humboldt Foundation grant to continue my research as a post-doc at the Technical University of Dresden. Since 2014 I have been also actively involved as research associate at the faculty of environmental sciences in Dresden in several project dealing with environmental sustainability.

«Renewable Energy and Water systems designed and managed as an integrated efficient system»

Abstract: Water and energy availability is a global concern, most in particular in regions as the ones around the Mediterranean Sea not connected to the electricity grid.In parallel with the energetic problem, water is a major challenge not only for regions with a warm climate or semi-arid and arid regions.
The integration of multi-source renewable, such as stand-alone hybrid photovoltaic- wind system with or without electrochemical storage, has acquired a relative maturity in recent years, both from a scientific or technological point of view.The same for water systems when they are studied separately.
Actually we develop original systemic methods to design and study, water and energy as an integrated system. The results are not the same when we design each part separately.The principal interests of such a system are the clean production on the place of consumption, the mutualisation of resources, energy and/or water storage, and the security of supply. The design method is based on a systemic view of point for the architecture, the sizing and energy management strategies, with experimental validation. An interest application of hybrid system dealing with water pumping and/or desalination is presented; witch represent an original problem when the problem of water and energy are related together especially for the electrical and hydraulic remote area. A particularly interest is dedicated for the development of a real time supervision and the energy and water management of the integrated system.

«From Hamiltonian Hopf-bifurcation to the control of limit cycles in underactuated mechanical systems»

Abstract: Mechatronic systems need the integration of mechanical, information, electronics, management, intelligence, and other interdisciplinary studies, which lead to complex applications. This complexity does not only appear in the system identification and modeling, but also it has a repercussion in signal processing and controller design. When the system complexity increases, it is difficult for researchers to describe its dynamic behavior. Therefore, the traditional methods used to analyze and control of such systems, have difficulties to respond to the requirements of this complexity. Bifurcation and chaos theory can be employed to classify different dynamical behavior arising in a mechatronic system. The main focus of this special session will be on the bifurcation and chaos theory and their applications in mathematical modeling, signal processing, and control of complex mechatronic systems.

This presentation is divided into four parts :

  1. What’s generalized Hamltonian systems
  2. Hopf-bifurcation analysis
  3. The control of non-linear Oscillations
  4. Application to the Inertia Wheel Inverted Pendulum (IWIP)

Keywords : Hamiltonian Systems, Non-Linear Oscillation, limit cycles, Hopf-bifurcation
