高精度伺服系统的机理研究

The Reseach of Mechanism for High Accuracy Servo System

本文讨论和分析了伺服系统的闭环和半闭环控制．并提出了利用双闭环控制来实现伺服系统的高精度控制。研究表明，双闭环控制能够实现稳定控制和提高控制精度。

Closed-loop and half-closed -loop control System are discussed and analysed and dual-closed-loop to high accuracy dontrol for servo system is presented in this parper. The investigation show that dual-closedled-loop can realize stable control, and improve control accuracy.
