针对一类含有未知执行器故障的飞行控制系统,提出了一种基于自适应控制分配的容错控制方法。该方法充分利用了多操纵面战斗机的冗余特性,通过在线自适应调整控制分配矩阵,解决了未知故障情形下的容错控制问题,且无需调整基本控制律。分配矩阵的调整规则由李亚普诺夫(Lyapunov)稳定性方法获得。通过一个多操纵面战斗机ADMIRE模型的仿真,验证了该方法的有效性。
Aiming at a kind of flight control system with unknown actuator failure, a fault-tolerant control method based on adaptive control distribution is proposed. This method takes full advantage of the redundancy of multiple control plane fighters and adaptively adjusts the control distribution matrix online to solve the fault-tolerant control problem under unknown fault conditions without adjusting the basic control law. The adjustment rules for the distribution matrix are obtained by the Lyapunov stability method. The simulation of ADMIRE model of a multi-control plane fighter verifies the effectiveness of this method.
