The Research Of The Satellite Formation Flying Physical Simulation System

For the design of the satellite formation flying physical simulation system,the paper focus on the overall design of the satellite formation flying physical simulation system, the control strategy design of the satellite simulator, and the research of path planning of the satellite simulator. This paper mainly includes the following:In this paper, the overall design of the satellite formation flying physical simulation system has been completed. The hardware system and the software system of the satellite formation flying physical simulation system have been designed, and have designed the links between the subsystems. The structural design and the electrical design of the satellite simulator have been completed. The software for the satellite simulator control has been developed. The design of the ground console and the development of the software for ground control system also have been completed.In this paper, the modeling and the control strategy designing of the satellite simulator has been completed. The thrust of the satellite simulator in the platform coordinate system has been derivate. PID controller is used as the controller of the satellite simulator. Actuator allocation strategy of the satellite simulator has been researched by add a constraint equation for avoiding the actuator saturation.The paper has researched the methods of satellite simulator path planning. Considering the execution of the actuator is weak, the paper researched path planning for single satellite. Considering avoiding Collision in the process of satellite formation flying, the paper researched path planning for multiply satellite by the theory of virtual potential field force, and proved the method can effectively avoid the collision by Mathematical Simulation.
