多操纵面飞机稳定非线性控制分配

Stable Nonlinear Control Allocation for Aircraft with Multiple Control Effectors

摘要:

针对多操纵面飞机具有冗余操纵面的特点,考虑操纵面的位置约束,对多操纵面飞机设计一个由上层控制律和动态控制分配律组成的非线性控制器,应用李雅普诺夫稳定性理论和LaSalle不变集定理分别证明了上层控制子系统、动态控制分配子系统和整个闭环系统的渐近稳定性。对某多操纵面飞机的仿真结果验证了方法的有效性。

Abstract:

For aircraft with redundant multiple control effectors, a nonlinear controller, which was composed of a virtual control law and a dynamic control allocation with position constraints of each effectors, was designed. Based on Lyapunov stability theory and LaSalle invariant set theorem, asymptotic stabilities of upper control subsystem, dynamic control allocation subsystem and overall closed-loop system were proved respectively. Simulation results showed the effectiveness of the proposed method.
