摘　　要：针对开关磁阻发电机(SRG)的高度非线性,建立了SRG自励模式下的非线性模型,并提出一种优化滤波环节和加入动态移相控制器(DSC)的改进型电压反馈控制方案,在负载变动较大的情况下实现电压脉动抑制,改善系统的负载自适应能力,并解决SRG重负荷运行时传统的电压反馈控制失效的问题。仿真结果证明了改进型电压控制方案的有效性。The nonlinear models of SRG in self-excited condition were established thanks to its highly nonlinear characteristics ,and an improved voltage feedback control scheme with a dynamic commutation shift controller （DSC） and a optimization filtering unit were proposed, in which the ripple suppression for great load changes could be realized and dynamic response ability of the system was enhanced, more importantly,the problem that traditional voltage feedback failed when SRG operate at heavy loads could be settled. Simulation results verify the effectiveness of the improved voltage feedback control strategy.
