The tracking control system consists of the agile two-axis gimbals as the coarse tracking system and the high performance fine-pointing-mechanism(fpm) as the fine tracking system with the optical coarse acquisition sensor and the optical fine tracking sensor. It applies for the aerial platform and the onground platform, and free-space optical communication has been carried out between them. In the conventional tracking control systems, the two-axis gimbals is combined with the narrow range actuator for the fine pointing control, and it has the role of the coarse pointing control based on the GPS position and the attitude of the platform. To improve the control performance of “this two-stage type”, especially during the motion of theRead More
