【Abstract】 In this paper, a novel DC speed control system has been introduced, the auto-disturbance rejection controller(ADRC) has been used in the speed loop. The inner disturbance and outside disturbance can be observed with ADRC, and use it to offset the system. The results of simulation test indicate that the ADRC has good dynamic performance and the strong robustness to load disturbance and no overshoot.更多还原
