Study on the DTC Performance Improvement Based on Fuzzy-PI Control

Abstract:

Article Preview

There exists some problems of flux ripple and the switching frequency uncertainty in the traditional Direct Torque Control (DTC) .In order to improve the low-speed performance of the Machine direct torque control system, fuzzy direct torque control system is set up through fuzzy controller to replace Smith flip-flop ,we use fuzzy PI controller take place of traditional PI controller, also we establish the simulation model in the Matlab/Simulink environment, simulation results show that torque ripple and current distortion is decreased by use improved programs, can prove the effectiveness of this strategy.
