Abstract
A large number of switch cabinets without a remote control is a main safety restriction in the electric power substation. The new structure with DC Servo Motor (DCSM) drive mechanism and reducer is utilized in the remote control device in this paper. A sliding-mode variable structure controller (SVC) based on the dynamic model is proposed to maintain a constant speed with the unknown load. The stability of the control algorithm is demonstrated by the Lyapunov criterion. The simulation and experiments show that the control algorithm has the characteristics of fast dynamic response, small overshoot, and strong robustness to external load torque disturbance and disturbance.
