A MODIFIED DIRECT TORQUE CONTROL FOR INDUCTION MOTOR DRIVES

This paper presents a modified direct torque control based on combination of hysteresis current control and space vector modulation for induction motor drives. This technique is characterized by simplicity and high performance flux and torque control in ac drive systems. The configuration of hysteresis current control and space vector modulation in direct torque control technique can reduce drastically the switching losses by implementing space vector modulation technique and produce a better stator current waveform by using a significant tolerance bandwidth of the hysteresis current control. The behavior of the proposed technique is fully verified by digital simulation using Matlab/Simulink and experimental implementation on dSPACE 1 104 system card.
