摘 要：Many challenges of modeling and control exist in the tail-sitter aircraft,including parameter uncertainty,highly coupling,nonlinearity,and external *** this paper,the model of a tail-sitter aircraft is simplified at the nominal condition to obtain the nominal linear invariant *** a robust controller based on the H control theory is proposed to deal with the attitude tracking control problem and decrease the effects of multiple *** is proved that the closed-loop system has robust stability,and the tracking error can converge to *** is shown that the proposed robust controller can maintain the attitude angle adjustment accuracy and robustness to the model uncertainty and external disturbance.
