Abstract:

The drive, measurement and control techniques of the fine tracking system are studied. The drive, measurement and control circuit are designed. Dynamic and static performance of the drive circuit is tested and calibration experiment of the measurement circuit is performed. The method of Fuzzy-PID controller is studied. The performance of the system is tested while a vibration source is applied to simulate the vibration of object. Results indicate that the system is good at fine tracking.

Key words: fine tracking system, fast steering mirror, PZT, PSD
