摘　　要：针对因环路中反馈信号丢失或异常而引起整个系统工作不正常,造成系统损坏或人员受伤的问题,设计一种高精度三环伺服系统安全控制策略。以某型光电跟踪设备的伺服控制系统为例,对系统进行介绍,分析安全控制策略,并给出原理图。该设备已成功应用于某型光电跟踪设备上,使用结果表明,该策略能有效提高伺服系统的可靠性和控制安全性。If the feedback signals lose or abnormal in the loop, it may causing whole system abnormal of work and cause system damage or people injured. Aiming at the proposed problem, introduce a security control strategy design realization of high accuracy triple-loop serve system. Taking the serve system of some type of electro-optical tracking device as an example, proposes an introduction of the system, an analysis of security control strategies and the principle chart. This device has been applied to certain type of electro-optical tracking device, and the practice results show that the strategies can improve the reliability and control security of the serve system effectively.
