Abstract :
Direct Torque Control (DTC) is becoming one of the most popular control methods for induction motors.This technique was introduced in the mid 1980´s for voltage fed PWM inverter drives.Matrix converter (MC) has been studied widely for its advantages over the traditional converters.It is gradually employed for applications with its maturity in theoretical studies.A novel control strategy is put forward in this paper, which properly combines the space vector modulation (SVM) of MC with the DTC of induction machine through PI regulation of flux and torque.It improves the control performance of system, especially for the torque at low-speed. Conventional principles of DTC and SVM of MC were described.Then the combination of the two was given in detail.Finally, the simulation research was carried out based on MATLAB.Simulation results demonstrating the effectiveness of the torque control response and the input power factor correction are presented.
