This paper shows the application of fuzzy PID control technique to reduce torque ripple in an induction motor employing Direct Torque Control (DTC). The performance of the proposed drive system is evaluated through digital simulation using MATLAB-SIMULINK package. The simulation results clearly depict the superiority of devised method over the SVM DTC.

in this paper, a Fuzzy logic based direct torque control (DTC) scheme for split phase induction motor (SPIM) is established. The induction motor has two sets of stator three-phase windings spatially shifted by 30 electrical degrees. The major disadvantage of conventional DTC is existence of high torque ripples. In this paper, we used a fuzzy logic controller to overcome this drawback. Simulatio...

Space Vector Modulation (SVM) based Direct Torque Control (DTC) scheme is used for a variable –speed direct drive Permanent Magnet Synchronous Generator (PMSG) in a wind power generation system. SVM Provides more flexibility for inverter voltage utilization, in order to compensate the torque and flux errors in a smoother way than conventional DTC. SVM based DTC maintains constant switching freq...
