摘　　要：针对处理一类线性不确定离散时间系统多重的、同时发生的、突变的舵机故障问题,提出了一种新的故障估计方案。该方案考虑了两种舵机故障模型:舵机卡死和舵机失效。所提出的舵机故障估计方案适用于为战机设计一个H∞容错飞行控制器,用于以零横向加速度跟踪飞机转弯角和俯仰率指令。仿真结果表明,采用H∞容错飞行控制器能够取得较好的控制效果。A novel fault estimation scheme is proposed to deal with multiple, simultaneousand abrupt actuator failures for a class of linear discrete-time systems with uncertainty. Considered actuator fault models include both the actuator-stuck fault and the loss of actuator effectiveness fault. The proposed actuator fault estimation scheme is applied to design a fault-tolerant H∞ flight controller for a combat aircraft in tracking bank-angle and pitch-rate commands with zero lateral acceleration. Simulation results demonstrate good performance by using the fault-tolerant H∞ flight controller.
