Abstract
The control system of DC servo digital three closed loop was founded on using TMS320LF2407A for improving digital servo system control result, providing a good solution for PWM signal generation, motor speed feedback and electromotor current feedback in servo system. And rotor position measure circuit, phase current measure circuit, driver circuit and safeguard circuit are given more description, and the corresponding hardware circuit is described.
