中文摘要：

在matlab／simulink中对一台三相12／8极开关磁阻发电机的变速恒压工作情况进行了建模仿真，通过SRMFEM建立了开关磁阻发电机非线性本体模型，这在一定程度上保证了仿真结果的准确性在自励发电模式下，通过对电压、电流的两点式闭环，探讨了变速恒压情况下开关磁阻发电机的动静态响应．仿真结果表明：开关磁阻发电系统在变速的情况下依然有很不错的发电特性．但是，在仿真结果中，同样也可以发现，因为开关磁阻发电机是一个多变量、强耦合的非线性系统，在能量转换的过程中，虽然有滤波电容的平波作用，输出直流电压的脉动还是无法避免，在一些应用要求较高的场合，须在动态响应和发电质量两者之间权衡优化控制策略及相关拓扑电路的设计是下一步研究的问题．

英文摘要：

Due to the characteristics of high reliability, wide speed scope with high efficiency, and low cost, Switched Reluctance Generator （SRG） system is suitable for applications in the field of variable-speed con- stant-voltage generation, such as wind power generation, flywheel energy storage, electric vehicle, aircraft power generator, and so on. In this paper, a nonlinear model of SRG was established by means of Matlab/ Simulink. Furthermore, a power generation plan of SRG about variable-speed constant-voltage generation control system was designed. Variable-speed simulation results show that the control system has favorable dynamic and static characteristics.
