| Abstract: | To improve the attitude control system of multi-flexible satellite,the controller design based on fuzzy neural network was studied in this paper. According to the attitude and flexible dynamic models,the structure of fuzzy neural networks controller(FNNC) and simplified learning algorithm were given out.The simulation results showed that FNNC had a good performance to the satellites' parameter changes and outside disturbances,which could meet the requirement of the attitude control for flexible satellite wi... |
