摘　　要：根据永磁超环面电机特殊的转子结构,建立了该电机的电磁参数方程,并推导了含行星轮转子位置信息的时变数学模型,应用状态空间法分析了该电机的周期波动特性。结合超环面电机的时变参数,完成了对其PI控制器的参数整定。结合行星轮自转引起的参数摄动,将闭环系统反馈得到转子位置信息引入到终端滑模控制器中,使控制器参数跟踪超环面电机的时变参数。将终端滑模控制与PI控制的仿真结果对比分析,结果表明:该控制策略有效地削弱了永磁超环面电机输出性能上的周期波动,并且具有良好的响应速度、抗干扰性和鲁棒性。According to the special rotor structure of permanent magnet toroidal motor(PMTM),an electromagnetic parameter equation of the motor is established.The time-varying mathematical model with the rotor position information of planetary gear is derived.The periodic fluctuation characteristics of PMTM are analyzed by using the state-space method.In combination with the time-varying parameters of PMTM,the setting parameter of PI controller is made.In combination with the parameter perturbation caused by the rotation of planetary wheel,the rotor position information obtained from the closed-loop system feedback is introduced into the terminal sliding mode controller,enabling terminal sliding mode control parameters to track the time-varying parameters of toroidal motor.The simulation results of terminal sliding mode control and PI control are compared and analyzed,and the results show that the terminal sliding mode control strategy weakens effectively the fluctuation amplitude of output torque of PMTM,and is good at response speed,in interference immunity,and in robustness.
