摘要：本文在利用Matlab/Simulink建立开关磁阻电机（SRM）物理模型和控制策略模型的基础上，通过仿真分析相电流变化与母线电流变化之间的关系，找出了SRM工作时母线电流剧烈波动的原因。为解决此问题，本文首先分析论证了使用LRC低通滤波器改善这种状况的可行性，然后选取合适的参数设计滤波器并进行仿真对比，最后，通过台架和实车测试，证明了该解决方案有效。

Abstract: Based on the physical model and control model of switched reluctance motor (SRM) which established by Matlab/Simulink，this paper analyzed the relationship between the phase current changes and busbar current changes，and then found out the cause of the SRM busbar current severe fluctuation at work. To solve the above problem, this paper analyzed the feasibility of reducing the fluctuation by using the LRC lowpass filter.By selecting appropriate parameters to build filter in the vehicle tests, this solution was proved effective.
Key words: switched reluctance motor;busbar current;LRC lowpass filter
