This paper presents a robust rotor speed sensorless control strategy for induction motor. The main purpose is to overcome the instability issue for zero/low speed operating mode while considering that the rotor resistance is subject to uncertainties or variations. A Modified Model Reference Adaptive System speed estimation scheme is presented, and its sensitivity to stator resistance mismatches is investigated. The proposed approach introduces a discrete reference and adjustable models of the motor. Moreover, an adaptive discrete speed estimation scheme is synthesized on the basis of the extended Kalman filter technique. The proposed sensorless control scheme is tested using the professional Hardware simulator AMEsim (LMS). The obtained results confirm the superiority and ability of the proposed method compared to the classic Model Reference Adaptive System speed estimation scheme to guarantee a …

In this paper, an efficient and fast MPPT power control of photovoltaic systems based on backstepping approach is presented. The proposed control scheme consists of two cascade loops; in the first loop, the auto-scaling variable step-size perturb and observe MPPT technique estimates the reference voltage of all electrical load values. The robust backstepping controller has been adopted to remove steady state oscillations in the second loop. Further, the performance of proposed control system has been analyzed through dSPACE DS-1104 experimental validation with Isofoton photovoltaic module under real climatic conditions at Biskra (Algeria) region. The results obtained by the used controller averred a good improvement.

The present paper investigates the effectiveness of Finite Set Model Predictive Current Control (FS-MPCC) for Shunt Active Filter SAF and its implementation on real bench. The method uses a Multivariable Filter MVF to extract the fundamental components of currents and voltages of the grid. The predictive control method uses a cost function containing the error of the filtered currents to be controlled. The performances of the control method are revealed throw simulation and experimental results and then commented. The obtained results show that predictive control is a powerful control method for such application in term of tracking performance and quality energy.

This paper presents a comparative study of two approaches for the direct power control (DPC) of doubly-fed induction generator (DFIG) based on wind energy conversion system (WECS). Vector Control (VC) and Sliding Mode Control (SMC). The simulation results of the DFIG of 5 KW in the presence of various uncertainties were carried out to evaluate the capability and robustness of the proposed control scheme. The (SMC) strategy is the most appropriate scheme with the best combination such as reducing high powers ripple, diminishing steady-state error in addition to the fact that the impact of machine parameter variations does not change the system performance.

Maximum power point trackers are so important in photovoltaic systems to improve their overall efficiency. This paper presents a photovoltaic system with maximum power point tracking facility. An intelligent Sliding mode controller method is proposed in this paper to achieve the maximum power point tracking of PV modules. The system consists of a photovoltaic solar module connected to a DC-DC boost converter. The system is modeled using MATLAB/SIMULINK.

The simulation results show that the proposed maximum power tracker tracks the maximum power accurately and successfully in all tested conditions. The MPPT system is then experimentally implemented. DSPACE is used in the implementation of the MPPT hardware setup for real-time control. Data acquisition and system control are implemented using dSPACE 1104 software and digital signal processor card. The experimental results show the efficiency of the proposed algorithm and confirm the simulation results.

In recent years, electrical energy has become a vital component for human life. Moreover, the interest for alternative energy sources has an exponential rise nowadays as a consequence of the limitation in conventional energy sources. Wind energy is considered one of the most important renewable energy sources. Nowadays, in order to ensure an optimal energy use, management and control technologies of wind energy conversion system are developed rapidly. In this paper, both of the vector controller and sliding mode control strategy for an isolated doubly fed induction generator-based wind energy conversion system are studied, described, tested and compared. In order to ensure the safety of the connected load, the main purpose of the present work is to maintain output stator voltage and frequency at their reference values whether for load demand power variations and wind speed fluctuations. Experimental results demonstrate the effectiveness of the presented control strategies.

The present paper deals with a real time implementation of a new adaptive frequency-based power management strategy of a small-scale hybrid battery-super capacitor system, dedicated to an electric vehicle. The ultimate objective of the strategy is to ensure a smart use of the two sources, improving as a consequence both the autonomy and the system lifetime. To do so, and unlike the conventional power frequency separation technique, the filter adapts its pass band frequency to keep the charge’s state of each source in a tolerable range and provides power amounts to the load demand. The experimental results demonstrate that the system commutates smoothly between the operating modes, which proves the effectiveness of the proposed control techniques.

The problematic is to study the management of a hybrid energy system, depending on demand, dedicated to self-governing houses. Energy can be supplied by a photovoltaic panel, a wind turbine and a diesel generator and it can be stored in batteries. The study of this type of systems requires a good control strategy and an effective management. The main objective of this study is to develop a reliable management model and to simulate the hybrid system of a house located in Monastir-Tunisia, with different domestic loads, such as a washing machine, freezer, refrigerator... A system of energy management that can adjust, optimize and adapt the consumption to the available energy resources while satisfying the request is then examined. Thus, to study the problem of energy management and reduce energy consumption and production of greenhouse gases, the definition off an analysis tool on MATLAB/SIMULINK has allowed the covering of load demand in an optimized manner using the optimal system chosen by HOMER.
