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.
Aiming at the control problem in the case of failure of the actuator of the aircraft kinematics system, which is modeled as the switching multi-cell model, an adaptive compensation control scheme is proposed.First, an adaptive adaptive multi-cell system Aiming at the problem of actuator failure and the failure value and failure mode unknown, an adaptive fault-tolerant control law is designed and combined with the common Lyapunov function and the average dwell time The method proves the stability of the closed-loop system, which solves the design problem of the fault-tolerant controllers in the multi-cell switched multi-cell system. The simulation results verify the good performance of the proposed scheme.
