Abstract
We establish the mathematical model of a motor-driven torque control simulator. Under the circumstance of passive load, we suppress the surplus torque by using the position-proportional control and angular-speed feed forward compensation. We design the control system that includes three loops: position-proportional control, angular speed feed forward compensation and closed-loop PID torque control. We then analyze the time domain and frequency domain characteristics of the control system. The results and their analysis show preliminarily that the control system thus designed can significantly enhance the control precision of the motor-driven torque control simulator and expand the frequency band of its torque load to at least 25 Hz.
