摘要: This paper deals with investigating the closed-loop stability boundary of highly flexible aircraft structural flexibility and input saturation constraint. A method is presented to analyze stable region based on system features open-loop instability. In this paper, a dynamic model made characteristics are analyzed long period mode investigated in terms trimmed model. Considering constraint elevator deflection, under discussed by combining instability aircraft. The analysis indicates that related left eigenvector consistent amplitude unstable poles control signals. Based aircraft, formula analytically obtained. convergence verified LQR controller. influence state constraints, which also compared rigid simulation results show restricted characteristic
