Abstract
A small electric servo position feedback system is designed, this system has fast response, small overshoot, stable performance, practical value of higher benefits. The working principle and compo- nents of the servo system are introduced, and then the key to the system control, secondary power supply circuit, reactive circuit as well as the H-bridge power amplifier circuit are analyzed emphasisly, the key technologies, key components which can affect the servo system performance and its control accuracy are analyzed and discussed.关键词
