摘　　要：基于开关磁阻起动/发电助力控制系统的研究背景,根据该系统具有严重非线性,转速给定多变、负载扰动大、参数变化多的特点,利用自抗扰控制原理设计了开关磁阻电机转速闭环控制系统。采用Matlab仿真软件,建立了该系统的仿真模型,并进行了控制策略设计和参数估算。由仿真结果可知,该系统对外部负载扰动和内部模型参数的变化具有较强鲁棒性能,比传统的PID控制系统动静态性能更优。最后在开关磁阻起动/发电样机平台进行的样机试验表明,自抗扰控制可以实现样机的快速、无超调起动,负载扰动时转速变化小、恢复时间短、转速跟踪快。According to the research background of reluctance switched integrated starter/ generator power-assisted system with nonlinearity, changeful reference speed, large load disturbance and variable system parameters, rotating speed close loop control system is designed by auto disturbance rejection control. The simulation model is given by Matlab. The control strategies are designed and the parameters are estimated using the simulation model. The simulation results show that the system has good robustness to external load disturbances and internal model change and it is better than the conventional PID control. By the switched reluctance integrated starter and generator prototype experimental platform, the results show that the system has fast and non-overshoot starting, small rotor speed change, short recovery time at load disturbance and rapid rotating speed tracking.
