Research On The Design And Simulation Of XX-1 Small Satellite Attitude Control System Based On The Integrated Platform

Attitude control system and integrated platfom for design and simulation are the key technologies in the development of modern small satellites.Under the background of XX-1 small satellite attitude control system and Matlab-RTLab integrated platform, a systematic and deep study on the attitude control system design and simulation was made in this dissertation. The main contents of this dissertation were the following parts.First, based on the functionsand requests of XX-1 small satellite, the deploy project of attitude control system was designed. The mathematic models of attitude sensors and performing parts of the system were created. Moreover, the work mode and safety measure were programmed. Then, the algorithms of attitude determination and control were designed.Afterward, the integated platfom based on Matlab-RTLab and the application of this integrated platform for design and simulation of small satellite attitude control system were studied. Furthermore, the dissertation discussed the technologies of automatic code generation based on the integrated platform and gived the validated and evaluated methods of the codes. Again, the closed-loop simulation and test technologies based on the integrated platform were studied.In the end, the attitude control system of XX-1 small satellate was simulated on the integrated platform, and the results were validated by analysis.The study results show that the project of XX-1 small satellite attitude control system fits into the requirements of design. The integated platfom based on Matlab-RTLab is applicable in the whole process of design, exploitation, simulation, testing of the satellite attitude control syetems. The technology of automatic code generation based on the integrated platform solves the problems in the software exploition by handwork, and it has an excellent applicable future.
