The position detection is the important link in the permanent magnet synchronous motor control. The accuracy of the detection is the key to the high performance control of the motor. Aiming at the problem of permanent magnet synchronous motor pole position difficult to detect, of permanent magnet synchronous motor position loop were in-depth analysis, and mathematical model as the basis, find out factors that can influence the precision of motor control, a design based on iterative algorithm for the permanent magnet synchronous motor position controller. The simulation results show that this method can improve the dynamic performance of the system and improve the tracking accuracy of the system, and it has some application value.
