摘　　要：本文以红外目标模拟器——周视镜工程实践为背景,讨论随动系统研制中常遇到的一些问题,并提出解决这些问题的方法。文中详细阐述随动系统常用的电动机、电位计、测速机及计算机等关键元器件与系统指标的关系,机械结构与系统指标的关系,以合理选取元器件,优化机械结构设计。作者力求从机械角度而不单纯从控制角度来探讨系统指标问题。本文还就模拟器的控制方案进行探讨,通过摩擦力矩补偿、H~∞补偿网络以及自适应前馈等各种技术措施,力求改善和满足高性能指标要求。经过实际应用的检验,充分表明这些技术措施的设计思想具有一定的工程实用和参考价值。This paper treats some typical problems of servo-systems and gives the solution of these problems, which is based on the example of the infrared (IR) Target Simulator——Panoramic Mirror. At first,the relationship between the system performance andthe main elements, such as motors, potentiometers, tachometers and computers is discussed, and how to select these elements is shown. Then the optimization of the mechanical structure is emphasized to improve the system. The control laws are also presented,such as friction torque compensation, H∞ control and adaptive feedforward control. The result of the application on-line has proved the practicality of approaches and the value of the paper.
