This paper mainly reviews the development of permanent magnet synchronous motor drive system. It presents several approaches of PMSM control strategies, including control strategies based on classical control, modern control and intelligent control. Theoretical background briefly describes the properties of these control techniques. Among these control strategies, vector control and direct torque control are considered as the mature methods for PMSM motors control currently. Advanced control strategies, with adaptive control, variable structure control and intelligent control included, improve the performance of PMSM in some respects, such as variations of plant parameters sensitivity, external disturbance and so on. It shows that the researches in this area are still a popular research topic. Finally, this paper prospected the foreground of the control strategies for PMSM.
