Abstract :
An improved and modified Direct Torque Control (DTC) algorithms for permanent magnet synchronous motor (PMSM) drive is investigated in this paper, which features low torque and flux ripple and almost fixed switching frequency. Indeed, a first algorithm uses DTC with Space Vector Modulation (SVM), which is called DTC-SVM, improves greatly the torque and flux ripples compared to the basic DTC reported in the literature. To minimise the calculation time of this modified DTC strategy and guarantee almost the same advantages of DTC-SVM, a novel algorithm uses DTC with Sinusoidal Pulse With Modulation (SPWM), which is named DTC-SPWM, is proposed in this study and compared to the basic and modified DTC. Simulation results, in Matlab/Simulink, demonstrate well the performance of the basic DTC and DTC-SVM and the effectiveness of the proposed control schemes.
