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.
