The invention relates to a permanent magnet synchronous motor control method based on an improved whale algorithm and BP-PID. The method comprises the steps that a permanent magnet synchronous motor control model of the electric vehicle is established, and a PID controller is established on the basis of the permanent magnet synchronous motor control model; establishing a BP neural network model and a PID controller setting model, and optimizing the BP neural network model by using an improved whale algorithm to obtain an optimized BP neural network model; optimizing the setting model by using the optimized BP neural network model to obtain an optimal PID control parameter; and controlling the permanent magnet synchronous motor control model through the optimal PID control parameter. The PID parameters are configured by using the BP neural network model, so that the problems that the algorithm robustness is poor and the application of the PID algorithm in occasions of high speed, high precision, large disturbance and the like is difficult to meet when the PID algorithm is used for controlling the PMSM of the electric vehicle can be solved; in addition, the BP neural network model is optimized by using the improved whale algorithm, and the convergence capability of the BP neural network is improved.
