An Adaptive Fuzzy Controller for Satellite Maneuver Control

An adaptive fuzzy controller for Satellite Maneuver Control （SMC） is outlined. The typical fuzzy controller has a quick transient response and a very good robustness quality, and can easily incorporate human expert knowledge in the form of fuzzy rule ＂intelligence＂. But to construct the fuzzy rule base we must hold enough expert knowledge in advance, sometimes it＇s a difficult work. So the adaptive method is incorporated into the fuzzy control system, thus by adjusting the parameters of the fuzzy system, a proper fuzzy rule base can be got. And because the analysis is based on the Lyapunov function, the system is insured to be stable. Comparison of the system＇s performances with no language information and with only one language information is given, shows that with only one language information the system can reach a very high quality. Finally, simulation results substantiate the robustness quality of the adaptive fuzzy control system.
