Permanent magnet synchronous motors have been widely used in electric vehicles because of their good performance and high energy conversion efficiency. mathematical models of permanent magnet synchronous motors in different coordinate system are built in the paper . Based on the vector control method of permanent magnet synchronous motor, a double closed-loop control system of permanent magnet synchronous motor is constructed. Combining fuzzy control theory and traditional PID control method, control rules are design according to control experience, PID parameters is set, and a new fuzzy self-adaptive PI control system are design in order to realize precise control of permanent magnet synchronous motor. The simulation models of traditional digital PID control and fuzzy PID control are built using Matlab/Simulink software, and the simulation experiment of the control system is carried out. The simulation results show that the proposed fuzzy PID control scheme can effectively improve the speed response speed and control accuracy, and has good stability and dynamic performance.
