Abstract :
Input-output (I/O) linearization is a typical control method in the nonlinear multi-input multi-output (MIMO) system. Adaptive fuzzy control is combined with input-output linearization control to constitute the hybrid controller. The proposed control method is applied to the attitude maneuver control of the flexible satellite, which is a complex nonlinear system. The basic control structure is presented. The selection of the controller parameter, which guarantees the attitude stabilization of the satellite with parameter uncertainties, has been analyzed. The adaptive fuzzy control compensates for the plant uncertainties to increase the robustness of the controller. Simulation results show that precise attitude control is accomplished in spite of the uncertainty in the system.
