Variable structure attitude control of flexible satellite
挠性卫星的变结构姿态控制

The input-output linearization control is combined with the adaptive fuzzy sliding mode control,and is applied to the attitude maneuver control of the flexible satellite.Firstly,the basic control structure is presented.The adaptive fuzzy control is then utilized to approach the nonlinear control part of sliding mode control,and the adaptive law is also derived.Morever,the parameter of the adaptive fuzzy control is adjusted on-line to deal with the satellite uncertainty,thus the robustness of system is obtained.Finally,simulation results show that precise attitude control is accomplished in spite of the uncertainty in the system.
