Abstract:

Abstract. Besides different field-weakening control algorithm during accelerating and decelerating process of permanent magnet synchronous motor, the control system proposed in this paper also combined Maximum torque/ampere control with field-weakening control methods. It not only satisfied the large torque and wide speed range requirement which was put on drive system by vehicle, but also improved the reliability of drive system. Modeling and simulation work of the drive system are also done with MATLAB, simulation results proved that the control system proposed in this paper is effective.
