基于关断角补偿的开关磁阻电动机转矩脉动抑制仿真

Simulation on Switched Reluctance Motor under a Fuzzy-logic-based Turn-Off Angle Compensation for Torque Ripple Reduction

针对开关磁阻电动机(SRM)转矩脉动大的问题,采用模糊控制器对开关磁阻电动机的关断角进行实时补偿,实现SRM关断角自动调节,从而达到减小转矩脉动的目的。采用Matlab／simulink仿真软件,构建SRM控制系统的仿真模型,进行仿真实验。实验证明了该方法的可行性和有效性。

To resolve the problem of torque ripple in a Switched Reluctance Motor, a fuzzy-logic-based turn-off angle compensator for torque ripple reduction was proposed. Turnoff angle was changed timely to reduce torque ripple. In simulink, a switched reluctance motor drive model block was set up and simulated Simulation results was presented. The reasonability and validity were testified by simulation results.
