Abstract:
For its inherent drawbacks of classic Direct Torque Control(DTC),such as torque,flux,and current ripple,a novel DTC scheme is presented,in which a sliding mode variable structure control(SMVSC) method is applied to control electromagnetic torque and stator flux by using torque and flux errors,in order to preserve the system states near the sliding-mode surface and reduce the reaching distance.For its intrinsic chattering of SMVSC,it suggested a hybrid sliding-mode variable structure control(HSMVSC) method,in which variable structure control(VSC) could smoothly transit to classic PI control by hysteresis comparator adapted.The experiment results verify its validity and effectiveness.
