In this paper, the problems of bandwidth matching, miss distance calculation and control loop coupling in the composite axis control system of optical communication terminal are analyzed and deduced in detail. Firstly, the relation between coarse and fine tracking bandwidth ratio is described. Secondly, the theoretical formula of miss distance under image rotation is derived by means of coordinate system transformation. Finally, a cooperative control strategy is proposed to achieve high precision tracking of the system. The accuracy and effectiveness of the above methods are verified by system simulation and test platform, which lays a theoretical and technical foundation for the application of the composite axis control system of the latent optical communication terminal. © 2022 IEEE.
