中文摘要:
      根据永磁超环面电机的结构特性和运行原理,推导了其结构参数和运动参数对电磁参数影响的表达式,建立了永磁超环面电机的数学模型并应用状态空间法进行了动态特性分析。针对该电机电磁转矩和输出转速的周期性波动,在转速环中通过模糊控制规则得到其结构参数与运动参数的增量以调节终端滑模控制器参数。为了提高永磁超环面电机的响应速度,应用直接转矩控制在转矩环和磁链环中设计了super-twisting滑模控制器,并结合空间矢量调制对永磁超环面电机进行控制。仿真实验表明:此控制策略有效地提高了永磁超环面电机的响应速度,减小了输出转速和电磁转矩的波动,得到了良好的控制效果。
英文摘要:
      In accordance with the structure characteristics and operation principle of permanent magnet toroidal motor, an expression is derived from its structure parameters and motion parameters as affected to the electromagnetic parameters. A mathematical model of permanent magnet toroidal motor is established and the dynamic characteristics are analyzed by using the state space method. According to the periodic fluctuation of electromagnetic torque and output speed of the motor, the increment of structure parameters and motion parameters is obtained by fuzzy control rules in the speed loop to adjust the parameters of the terminal sliding mode controller. In order to improve the response speed of the permanent magnet toroidal motor, a super twisting sliding mode controller is designed in the torque ring and flux ring by using the direct torque control, and the permanent magnet toroidal motor is controlled by combining the space vector modulation. The simulation results show that the control strategy effectively improves the response speed of the permanent magnet toroidal motor, reduces the fluctuation of the output speed and the electromagnetic torque, obtaining a good control effect.
