Item Direct Torque Control of Three phase Induction Motor drive using Fuzzy Logic controllers for low Torque ripple(2013) Idir, A.; Kidouche, M.This paper presents an improved Direct Torque Control (DTC) based on fuzzy logic technique. The major problem that is usually associated with DTC drive is the high torque ripple. To overcome this problem a torque hysteresis band with variable amplitude is proposed based on fuzzy logic. The fuzzy proposed controller is shown to be able to reducing the torque and flux ripples and to improve performance DTC especially at low speed. The validity of the proposed methods is confirmed by the simulative resultsItem Real-time simulation of decoupled power control scheme for wind turbine applications by using RT-LAB package(IEEE, 2017) Ahriche, A.; Idir, A.; Boussoufa, A.; Kidouche, M.; Mekhilef, S.This paper presents a real time simulation of doubly-fed induction generator (DFIG) control for wind turbine generation system (WTGS). A decoupled power control based algorithm is used to drive the whole system. Where two PI controllers are designed in order handle the active and reactive powers, while a third one is employed to keep a same voltage in the DC-Link. In order to verify the whole algorithm, a real-time simulation is done by means an RT-Lab package which represents a suitable hardware and software for this kind of applicationsItem Rt-lab and dspace : two softwares for real time control of induction motors(Editura Academiei Romane, 2014) Idir, A.; Kidouche, M.
