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.

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.
