摘要：This paper presents plugging operation of induction motor drives for stopping and speed reversal.Classical direct torque control (CDTC) is known to produce quick and robust response in induction motor drives.However, during steady state, notable torque, flux, and current pulsations occur. They are reflected in torqueestimation, speed response, and also in increased acoustical noise. A new direct torque and flux control based on spacevectormodulation (DTC-SVM) is proposed for induction motor drives, in comparison with the classical DTC methodthe inverter switching frequency is constant and is dramatically increased, requiring neither any increase of thesampling frequency, nor any high frequency dither signal. The constant switching frequency approach to direct torquecontrolled induction motor drive results the reduced torque, current and flux ripple.
