IntroductionIn 1 980 s,Professor Depenbrock proposed aunique control scheme called direct torque control( DTC) for induction motor,which combined sim-plicity and robustness with excellent performanceof torque control for AC drive system[1,2 ] . Theprogress in power electronics and microprocessortechnology made higher inverter switching frequen-cy possible,which directly leads to the betterchar-acteristics of the DTC system.The DTC simulation system based on MAT-LAB is established in th… 相似文献
