Simulation Analyses for Suppresion Method of SRM Torque Ripple Based on Five-level

介绍了五电平拓扑下的直接瞬时转矩控制原理,在此基础上,建立基于五电平的开关磁阻电机直接瞬时转矩滞环控制策略Matlab/Simulink仿真模型,重点介绍转矩滞环控制器、开关表的制作与模型建立。仿真结果表明,和直接转矩控制、三电平拓扑下的转矩滞环控制相比,五电平转矩滞环控制策略有效地抑制了电机转矩脉动。

Five-level converter of direct instantaneous torque control is introduced. Torque hysteresis control strategy for switch reluctance motor is designed under five-level converter, and build simulation models in Matlab/Simulink. Torque hysteresis controllers, and build switching table are described focally. The simulation results show that, compared with the direct torque and three-level, torque hysteresis control strategy under the five-level converter can effectively suppress torque ripple.
