A proportional-feedforward position controller based on tracking-differentiator of PMSM

摘要

This paper proposes a proportional-feedforward position controller based on tracking-differentiator for a permanent-magent synchronous motor(PMSM). The proposed position control algorithm can effectively improve the performance of servo system, without producing overshoot. And to further accelerate the response under a wide range of step commands, the saturation of position regulator is utilized to help arranging the transient process of position commands. Simulation results indicate that the designed controller for servo position control system satisfies the designed requirements of fast response without overshoot.
