Abstract :
This paper focuses on designing a robust fuzzy multivariable controller for the attitude stabilization system of a flexible satellite. Fuzzy control is combined with LMI-based H∞ output feedback methods to suppress the interaction of rigid-elastic coupling modes. The proposed method can afford to reinforce the precise pointing capability of satellites under parameter varying space missions, because its control structure reformulated on fuzzy cells offers the blending of sub-optimal control laws
