摘　　要：在开关磁阻发电机（SRG）实际工作特性的基础上，建立了SRG非线性数学模型，并提出一种电压反馈控制结合励磁角度位置控制的方案，能够针对电机恒功率区域内电压反馈控制失效的问题进行补偿，在电机全转速范围内实施分段控制：中低转速区间，采用基于滤波优化的电压反馈控制器抑制电压脉动；高转速区间，采用励磁角度的闭环控制对输出电压进行调节。仿真研究表明基于该控制方案的SRG闭环系统可以输出质量良好的电压，幅值平稳，脉动理想，动态响应迅速，证实了控制策略的有效性。According to the actual operation characteristics of Switched Reluctance Generator （SKG）, the nonlinear mathematical model are established, .and a control scheme of combining angles position control with voltage feedback control is proposed which can effectively compensate the problem that the voltage feedback is failed in constant power area of the machine. The control method is implemented in subsection： whe：. oizG operates with low or medium speed, the feedback controller based on filter optimization adopted to restrain output voltage ripples; accordingly, the closed-loop control of excitation and is used to regulate output voltage of SRG when operates beyond rated speed. The relevant simulation results show that SRG system can produce excellent electric energy, which contains smooth amplitude, little ripples, fast dynamic response. All simulation researches testify the feasibility of the control method proposed.
