Researches of micro-satellites' multidisciplinary modeling and simulation based on software interfaces

Micro-satellites are complex systems, constituted by several disciplinaries, and there are complicated multidisciplinary coupling relationships between different disciplinaries. Aiming at modeling and simulation of micro- satellites, a scheme for multidisciplinary modeling and simulation of micro-satellites, based on commercial softwares such as STK, ADAMS, ModelSim, Matlab/Simulink and so on, was proposed. The architecture of the modeling and simulation platform was also given. Then some key techniques such as coupling modeling, software interface and co-simulation were proposed and solved. At last, a prototype system composed of attitude control, structure dynamic and power supply was built, and a large angle maneuver of the prototype was simulated. The simulation result verifies the efficiency of modeling method and the feasibility of the platform.
