| Abstract: | To satisfy the requirements of APT （Acquisition, Pointing and Tracking） system in space optical communication, a control system with three-loop strategy is proposed in this paper, based on the improved PID algorithm. As well as the hardware and software designs are elaborated according to the mathematical model of the system, the fault tolerant method is discussed at the same time in order to deal with the space environment. The simulation and experiments show that the proposed approach is reasonable and easy to be implemented on hardware. |
