The simulation results show this control system has good dynamic property and negligible vibration, and efficiently makes the output current of directmotor trace the intent current.
It is digital servo timing control system which is driven by PWM, directcurrent moment motor.
采用了脉冲调宽功放装置(PWM)，直流力矩马达直接驱动转台框架的数字伺服调速体制。

It analyzes and compares the directcurrentmotor drive system and AC motor drive system and includes the theory of motor running, at last we bring forward some solutions to control the torque.
