摘要
深入研究现代飞机大迎角下的非线性动力学特性是当今飞行力学的重要研究内容。综述了非线性动力学系统定性方法中分叉问题的基本概念、数值计算方法和相关软件,重点介绍了分叉分析方法在飞机开环、闭环非线性动力学特性分析和大迎角控制律综合以及分叉控制方面的应用。
Extensive investigation into nonlinear dynamics of a high AOA aircraft came to be of great importance in modern flight dynamics. The basic concepts and numerical algorithms of nonlinear bifurcation methodology are reviewed as well as related software. Highlights are given to the application of bifurcation methodology to open loop & closed loop dynamics analysis of aircraft model together with control law synthesis and bifurcation control at high angle-of-attack.
