Abstract

Due to the problem of torque ripple in low-speed range of direct torque control for induction motor,the torque was well controlled by using the strategy of giving the torque priority and designing the three-band adjustor with choosing the appropriate Park vector of voltage.The simulation model of direct torque control system for the induction motor based on MATLAB/Simulink was constructed,and the low-speed range characteristics were studied.The simulation results showed the correctness of the model and the validity of the control system.
