电动汽车用SRM调速系统的分析与仿真

摘要

Combining the control schemes with corresponding speed status, the paper simulates and analyses the SRM regulation system popularly applied in electrical vehicle, and then concludes the result. The paper details each speed regulation status of SRM, emphases the opening angle, the closing angle and conduction angle of electric device used in different control schemes with corresponding speed status. The paper gives the single phrase simulation diagram and state the rated value of electric device. At the final of paper, the starting, regulating and braking stages of SRM are given with controlling methods put in to draw the conclusion and prove the controlling status applied in speed regulation to be effective.%对越来越普遍应用于电动汽车的SRM的调速系统进行分析和仿真,并结合控制策略对相应的运行状况进行电路仿真并得出结论.详细介绍了开关磁阻电机的运行状况,重点结合SRM不同运行阶段的控制策略,对器件的开通、关断和导通角的要求进行介绍与分析.对单相控制的电路原理进行仿真分析,并对器件进行定额；通过结合控制策略对四相8/6极SRM的启动、调速、制动运行状态进行分析,得出SRM结论,说明控制方案的有效性.
