摘要： 针对具有多工作点的飞机,基于Lyapunov理论提出了一种多目标飞行控制器设计方法.在存在未知系统参数条件下,该方法同时考虑了飞机的操纵品质要求和鲁棒稳定性.利用线性矩阵不等式(LMI)方法推导了多工作点飞行条件下的操纵品质准则.基于参数相关Lyapunov函数和描述系统方法,得到了飞行控制系统鲁棒稳定性条件.飞行控制器设计方法可以归结为求解一组线性矩阵不等式.仿真结果验证了设计方法的有效性.

Abstract: The design of a multi-objective flight controller for an airplane with multiple operating points (MOP) is proposed via Lyapunov theory, which takes account of the requirement of handling quality and robust stability simultaneously with unknown system parameters. A criterion is derived by the linear matrix inequality (LMI) approach for all flights corresponding to multiple operating points. Based on the parameter-dependent Lyapunov functions in combination with a descriptor system, a robust stability condition is given for the flight control system. In this way the design of flight controller can be attributed to the solution to a set of LMIs. The simulation result verified the effectiveness of the design method proposed.
