Abstract:  To improve the deficiency of traditional PID locating algorithm accuracy, a new PFC-PID locating algorithm was put forward. PID control was used in speed loop to resist interference. PFC was used in position loop to improve track accuracy. Experiments were done on a PMSM. The result shows that the locating accuracy is enhanced greatly. The system has strong robust characteristic.
