By using the direct torque control (DTC), robust response in ac drives can be produced. Ripples of currents, torque and flux are oberved in steady state. space vector modulation (SVM) applied in DTC and used for a sensorless induction motor (IM) with fuzzy sliding mode speed controller (FSMSC) is studied in this paper. This control can minimize the torque, flux, current and speed pulsations in steady state. To estimate the rotor speed and stator flux the model reference adaptive system (MRAS) is used that is designed from identified voltages and currents. The FSMSC is used to enhance the efficiency and the robustness of the presented system. The DTC transient advantage are maintained, while better quality steady-state performance is produced in sensorless implementation for a wide speed range. The drive system performances have been checked by using Matlab Simultaion, and successful results have been obtained. It is deduced that the proposed control system produces better results than the classical DTC.

The climate in Algeria can be considered semiarid in most areas. The water demand is expected to increase because of population growth in the coming years. Water supply is always a great concern for the populations in the landlocked regions. Pumping water using the solar photovoltaic energy is a well-suited solution where the traditional electricity grid is absent. Indeed, the majority of these regions are very sunny, and water is available in underground aquifers. Our system consists on a photovoltaic generator (PVG), a direct current (DC)-DC converters, a multilevel inverter with five levels, and an asynchronous motor coupled to a centrifugal pump. The objective of this process is to ensure the operation at maximum power of the PVG system under various conditions by the maximum power point tracking (MPPT) method based on fuzzy logic control (FLC). The modeling and simulation of this system were carried out and based on our experimental work in the site meteorological database of city Adrar in Algeria. This system avoids the use of a motor pump (diesel) and eliminates costs and operating constraints in an environment friendly manner according to the COP21 recommendation.

“…DTC was introduced by Takahashi (1984) in Japan and then in Germany by Depenbrock (1985) [33][34][35][36][37][38] and has proved to be a powerful method for the control of induction machines. As compared to stator flux oriented control or field oriented control (FOC), DTC implementation minimizes the use of machine parameters 32,9,[39][40][41][42] while conserving the merits of fast transient response characteristics, it provides a systematic solution to improve operating characteristics of the machine and voltage inverter source 43 .…”
