摘要
概述了国内外直流PWM伺服控制技术的研究现状，讨论了PWM功率放大器的几种工作模式，进行了双极模式对低速非线性的改善和理论研究。
The researching aspects of the PWM servo control technology both at home and abroad are summarized,The paper discusses the working modes for the PWM driver,and also points out that the bipolar mode can jmprove the low-speed nonlinear for the PWM servo control system.
