摘　　要：针对开关磁阻发电机输出电压脉动问题,分析了开关磁阻电机发电运行原理,研究了开通角对发电性能影响,设计了直接用于开通角补偿的模糊逻辑控制器,建立了基于自励发电模式的SRG电压反馈控制系统模型,进行了输出电压建立,负载突加和突减仿真研究,与传统PI控制方法相比,模糊逻辑控制算法能有效抑制输出电压脉动,系统的动静态性能良好。For the problem of the voltage ripples of the switched reluctance generator, the principle of switched reluctance generator was analyzed. The effect of the turnon angle to the power performance was re searched. A fuzzy logical controller used to compensate the turnon angle directly was designed. The model of the voltage feedback control system based on the selfexcitation mode was established. The foundation of the voltage, the load increase and reduce suddenly was simulated. Compared with the PI control, the results of the simulation indicate the fuzzy logic method can a better performance in both static and dynamic. restrain the voltage ripples effectively and the system has
