摘　　要：随着光电探测与制导伺服机构对精度和响应速度要求的提高,传统伺服机构中诸如间隙、空回、磨损及摩擦等现象逐渐成为制约系统性能提高的主要因素。分析了高精密光电探测装备在车辆、舰船、飞机等载体上应用现状与未来需求,指出了光电探测装备伺服机构技术发展中面临的挑战和设计制造瓶颈,阐述了加强对精密传动机构的精度与动力学特性分析、机构制造、机械与控制集成设计方法等方面研究的重要性,并针对影响伺服机构性能的若干重要问题,提出了相应的研究策略与思路。With the ever demanding requirements of servo mechanisms for high precision and large slew rate in sophisticated detection and targeting systems,servo error sources such as gap,backlash and friction become limiting factors for the improvement of servo performance.The requirements of the cutting edge servo mechanisms for different electro-optical targeting systems on various platforms were investigated,which include missile,warship and aircraft applications.Major problems and challenges in designing and manufacturing precise servo mechanism were studied,and several key topics were put forward for the development of the precise servo mechanism,including error budget and dynamic analysis,design and manufacture,integrated mechanical-control design method.Finally,future work is suggested for developing precise servo mechanism.
