Abstract

In this paper a new permanent magent synchronous motor (PMSM) rotor position estimate algorithm is discussed. The algorithm adjusts the estimated rotor position PI controller, makes the rotor back electromotive force produced by rotor permanent magnet on d axis veins. Compared with other PMSM position estimate algorithms, the algorithm has a higher dynamic performance and realizes stable rotor position / speed estimate even under high speed and load variations. The implementation of this algorithm is very simple, it does not change the original control algorithm structure of motor driver, and only consumes very little computational resources and is very suitable for low-cost PMSM driver system whose resources are limited. And the algorithm is robust to parameter variation. The algorithm has been test in the motor driver system of manned self-balancing vehicle.
