The aim of this paper is to present a simple Maximized Power Control for Wind Energy Conversion System (WECS) using Double Fed Induction Generator (DFIG). The control algorithm uses Sliding Mode Control technique (SMC), by the way of the machine inverter. This control strategy, based on stator flux orientation, tracks the maximum power for different wind speeds, and regulates separately the active and reactive powers exchanged between the machine and the grid. The control of our system is tested under fault condition by simulation. Some results are presented and discussed to prove simplicity and efficiency of the DFIG control for WECS.

Gray-Box models (GBM) which combine a priori knowledge of a process -e.g. first principle equations- with a black-box modeling technique are useful when some parameters of the first-principle model -normally time-variant parameters cannot be easily determined. In this case the black-box part of the GBM can be used to model the influence of input and state variables on the evolution of those parameters. The most commonly used black-box technique for GBM is Artificial Neural Networks (ANN). However Support Vector Machine (SVM) has shown its usefulness by improving over the performance of different supervised learning methods, either as classification models or as regression models. In this paper, a kind of SVM -the Least-Square Support Vector Machine (LS-SVM)- is used to develop a GBM for a Continuous Stirred Tank Reactor (CSTR) process. The aim of the present work is then to build a GBM to estimate a time-varying parameter, ρ, of the CSTR process. Good results confirm that SVM can be effectively used for developing GBM to estimate time-varying parameters of non-linear processes like CSTR.

In the modeling context, a dynamic system that represent the model of a phenomenon by incorporating both continuous and discrete times might give more realistic results.i.e, that time contains closed set of arbitrary real values called “time scales” and denoted by T. In this paper, the stability of class of switched linear system modeled in time scale T = Pa,b is examined, where the length and the gap of closed intervals union are a and b respectively.

This paper investigates the problem of fault detection and isolation (FDI) design for nonlinear Takagi-Sugeno (T-S) models with measurable premise variables. The provided approaches are easily formulated in terms of Linear Matrix Inequalities (LMI) problem, based on Lyapunov theory. This latter introduces “virtual” dynamics both in the output error and the observer gain matrices. The strategy is illustrated using a non-linear model of a doubly fed induction generator (DFIG) for a wind turbine, affected by current sensor faults. In order to illustrate the applicability and the effectiveness of the proposed approaches.

We propose a simple model of full and reduced linear “Luenberger-type” fractional-order observers for commensurate linear fractional-order systems in time and frequency domains, in the case where the measurements are not affected by disturbances. The design process of observers is determined from the solution obtained in time domain, the observer gains are computed by solving Linear Matrix Inequalities (LMI) following the fractional-order value (0 <; α <; 1 or 1 ≤ α <; 2) of system and ensure convergence of the observation error. The frequency procedure design is derived from time domain results with the aid of the factorization approach, where we define some useful coprime factorization. Then the linear fractional-order observers and their estimation error dynamics which are parametrized in the frequency domain.

This paper deals with the analysis and control of multicellular converter from the point view of hybrid theory. Therefore, a hybrid model, called hybrid automaton, should be established. The hybrid automaton for the multicellular converter is derived based on some properties obtained by the analysis of the open loop trajectories. Based on the obtained hybrid automaton, we derive a switching control law that guaranties the quadratic stability of the switched equilibrium. The continuous Lyapunov function used for the quadratic stabilization is the stored energy in the inductor and the capacitor. The switching surfaces are defined based on the highest rate of decrease of the continuous Lyapunov function. Simulation results bring out the advantages and the effectiveness of the proposed control scheme under fast variations of the input voltage and load resistance.

The synthesis of state feedback controller problem for the class of linear continuous-time systems with time-varying delay is solved by maintaining the positivity of the studied system in the closed-loop. Our state-feedback law is formulated by giving sufficient conditions in terms of LMIs. A numerical example with two types of time delay function is used in order to show the effectivness of our proposed method.

The purpose of this article is to demonstrate the interest and the need to rely on modeling and simulation of mechatronic systems in case of testing application and to contribute to the “democratization” of the use of models and “virtual testing”. Indeed, the systems are becoming increasingly complex: more dynamic, more optimized. Add for that the development schedules are more and more restricted with reduced budgets. These constraints which are antagonistic tend to emerge a new generation of designing and testing: the “virtual test platform”. We propose industrial methods and appropriate tools to develop this virtual test platform. It is with this objective that CERTIA (Provider of test benches and studies) and the company AIRCELLE (designer and integrator of nacelles), with significant experience in their respective fields, have developed the platform “PRESAGE” for virtual testing.
