摘要
用分支分析方法分析了不同构型飞机的深失速特性,用反向积分技术计算了深失速吸引子的吸引域。然后分别用李雅普诺夫方法和滑模反控制方法设计了两种深失速改出控制律,即俯仰振荡控制律与滑模反控制律。通过分析比较,得出了两种控制律之间的内在联系。最后分析了影响深失速改出特性的主要因素。
The deep-stall characteristics of different aircraft configurations are analyzed with bifurcation analysis methods, and the convergence regions of a deep-stall attractor are constructed with backward integration techniques. And then two deep-stall recovery control laws are designed： pitch oscillation control law based on the Lyapunov method and slide modeling anti-control law based on the slide modeling anti-control technique. By the analysis and comparison, the inner relationship between the two control laws is obtained. Finally, the main factors that influence the deep-stall recovery characteristics are analyzed.
