为了满足光电跟踪系统高精度跟踪的要求，针对一种新型内外框架式快速反射镜进行了详细的伺服系统设计。首先，对新型快速反射镜进行了数学建模，采用速度环与位置环相结合的双闭环控制方法，对位置校正环节和速度校正环节进行了参数设计。其次，以DSP为实现平台，详细阐述了快速反射镜伺服系统的硬件组成。再次，对快速反射镜伺服系统的工作模式和软件工作流程进行了详细说明。最后，为了验证快速反射镜伺服系统的性能，进行了锁零实验和跟踪实验。实验结果表明：快速反射镜锁零时响应快速且稳态误差小于0.3"，跟踪时跟踪误差均方根小于7"。新型快速反射镜伺服系统能够满足光电跟踪系统对快速反射镜的快速性和高精度要求。

In order to satisfy the high precision demand of photoelectric tracking system, a servo system was designed for a novel fast-steering mirror in detail. Firstly, the mathematic model of fast-steering mirror was established. A method of combination of velocity closed loop and position closed loop was adopted for the servo system of fast-steering mirror, and the parameters of the position compensation and the velocity compensation were designed. Secondly, the servo system was realized based on DSP. And the constitution of the servo system was expatiated clearly. Thirdly, the two working modes and the software working process of the servo system of fast-steering system were all described. Finally, the fixing point experiment and the tracking experiment were finished to verify the performance of the servo system of fast-steering system. Experimental results indicate that the response of the fast-steering servo system is very fast, the stable error of which is less than 0.3" in the fixing point experiment. And the mean square root of the tracking error of the fast-steering servo system is less than 7" in the tracking experiment. The servo system for the novel fast-steering mirror can satisfy the system requirements of high precision and fast response for the photoelectric tracking system.
