飞行器切换多胞系统执行机构失效自适应补偿控制

针对建模为切换多胞模型的飞行器动力学系统执行机构失效情况下的控制问题，提出一种自适应补偿控制方案。首先针对存在不确定的飞行器大包线切换多胞系统设计一种自适应增益调度控制器，以保证全包线稳定飞行；然后，针对存在执行机构失效、且失效值和失效模式未知的情形，设计一种自适应容错控制律，并结合公共Lyapunov函数和平均驻留时间方法证明了闭环系统的稳定性。该方案解决了飞行器切换多胞系统容错控制器设计问题。仿真结果验证了所提出方案的良好性能。

Adaptive actuator failure compensate control for switched polytopic system of flight vehicles

An adaptive compensate control scheme is proposed for the flight dynamic system in the presence of actuator failure, where the system is modeled in switched polytopic style. Firstly, an adaptive gain-scheduled controller is designed for the uncertain switched polytopic system of flight vehicles with the large envelope, which guarantees the stability in the whole envelope. Then, aiming at the problem of actuator failure with its unknown value and mode, an adaptive fault-tolerant controller is constructed, and a kind of method combining the common Lyapunov function and average dwell time is proposed to validate the stability of closed-loop system. The scheme proposed solves the fault-tolerant controller design problem for the flight vehicles switched polytopic system. The simulation results show the good performance of proposed method.
