摘要: 结合扩展分支分析(EBA)和模糊逻辑控制(FLC),提出了一种新的闭环分支控制方法,即EBA-FLC方法,并将其应用于某机动飞机的无侧滑滚转机动研究。揭示了飞机全局非线性动力学特性,实现了无侧滑滚转机动的闭环分支控制,使飞机在大范围内具有期望的动力学特性,改善了飞机无侧滑滚转机动的动态和稳态特性。

Abstract: The EBA-FLC technique, which is developed by integrating the extended bifurcation analysis with fuzzy logic control in this article, is a new close-loop bifurcation control method. The EBA-FLC technique is used to investigate the global nonlinear behavior of a maneuverable aircraft in zero sideslip roll maneuver. It turns out that the controlled aircraft has a desired dynamic behavior in wide range of the bifurcation parameter, and that the dynamic and static characteristics of the zero sideslip roll maneuver are both improved.

Key words: nonlinear flight dynamics, bifurcation control, BACTM, FLC
