Permanent Magnet Synchronous Motor(PMSM)is widely used in new energy vehicles,household appliances,industrial equipment and other fields due to its high efficiency,compact structure and high precision control.However,the motor will be affected by temperature,current,magnetic field and so on during operation,resulting in low anti-interference ability and poor dynamic response.In order to improve the speed tracking ability and stability of PMSM,a PI controller based on whale optimization algorithm(WOA)is designed in this paper.The PMSM model was established in Simulink.Based on PI velocity loop,traditional PI control and WOA-PI control are used respectively.Through simulation comparison,WOA-PI has better stability and responsiveness when the motor starts without load and the speed signal changes.
