Abstract：In the active disturbance rejection control (ADRC) system for the permanent magnet synchronous motor (PMSM),a good control performance can be gotten when the control gain is known.An estimated control gain,used in the ADRC controller when the control gain of the system is unknown,will affect the control performance.In this paper,the ratio between the estimated control gain and the real control gain is defined as the control gain ratio,whose effects on the step response,the noise immunity,the ability of rejecting disturbance,and the performance of continuously tracking the varying input is also analyzed.Theoretically analysis indicates that the shorter rising time of the step response and the better noise immunity while the worse disturbance rejection ability will be acquired with higher control gain ratio.Meanwhile,the advanced tracking performance will be achieved when the ratio approaches one.The Extensive simulation and experiment tests are performed to verify these conclusions.
