Abstract

Abstract

In order to improve the energy utilization efficiency of the optical antenna and realize the space laser communication networking, we study the mirror linkage tracking control technology. The principle of system composition is described, and a mirror linkage tracking control strategy based on a single-detector multi-actuator is discussed in detail. By analyzing the energy of a laser link, its linkage tracking constraints and error requirements are obtained. A mathematical model of double mirror linkage tracking is established. The servo controller is designed and simulated, and the prototype is built to test its tracking performance. The experimental results show that the system can track the target stably, the tracking target accuracy is better than 83 μrad, the double mirror linkage accuracy is better than 26 μrad and the received optical power of the system is significantly improved. The research in this paper lays a foundation for space one-to-many laser communication link networking.
