摘　　要：提出了用复合轴瞄准控制方法实现卫星光通信跟瞄控制 ,以提高卫星光通信中跟瞄系统的性能。提出了粗瞄和精瞄系统的模型 ,并分别设计了控制器。在此基础上 ,建立了一套跟瞄控制模拟系统。结果表明 ,所设计制作的跟瞄模拟系统在跟踪的匀角速率运动时的最大跟踪角度偏差仅为 14 μrad。A proposal is introduced in the paper that the control method of multiple axis pointing can be used to improve the tracking and pointing system in intersatellite optical communication.The models of coarse pointing and fine pointing are set up,and then a controlller is designed.Based on the above conditions,a simulation cocntrol system in the laboratory has been built.It shows that the maximal angular error of the system is 14μrad while the tracked target moving at an even angular speed.
