The invention discloses a CPC-based electric vehicle five-phase induction motor pole-changing control system, belongs to the field of high-performance multi-phase induction motor control, and designs an improved current predictive control current controller for an electronic pole-changing five-phase induction motor. Firstly, a current loop controller is designed based on the CPC theory so as to improve the dynamic responsiveness of the motor. Secondly, an extended state observer (ESO) is adopted to improve the CPC so as to ensure the steady-state performance of the controller; finally, compared with an improved CPC based on an electronic pole-changing five-phase induction motor and based on a PI current controller, a simulation result shows that the algorithm is higher in dynamic response speed and smaller in overshoot under the same condition, and meanwhile, the steady-state performance and PI current control are also superior.

    本发明公开了一种基于CPC的电动汽车五相感应电机变极控制系统,属于高性能多相感应电机控制领域,包括设计了一个用于电子变极五相感应电机的改进电流预测控制电流控制器。首先基于CPC理论设计了电流环控制器,以提高电机的动态响应性。其次采用扩张状态观测器(ESO)来改进CPC,以保证该控制器的稳态性能。最后基于电子变极五相感应电机比较改进的CPC和基于PI电流控制器,仿真结果表明所提算法在同等条件下动态响应速度更快且超调量更小,同时稳态性能和PI电流控制同样优越。
