本文利用线性矩阵不等式（LMI）方法和自适应方法研究了针对执行器故障的飞行跟踪控制问题。提出了一种自适应容错飞行控制器设计方法，该方法基于对可能发生的故障进行在线估计，并在正常控制律的基础上增加一个新的控制律，从而在不需要故障检测与隔离（FDI）机制的情况下降低故障对系统的影响。在线性矩阵不等式方法的框架下，对所得到的闭环系统的正常跟踪性能进行了无保守性的优化，并且故障模式的状态渐近地跟踪正常模式的状态。给出了一个F - 16飞机模型的数值例子及其仿真结果。
This paper deals with the problem of flight tracking control against actuator faults using the linear matrix inequality (LMI) method and adaptive method. An adaptive fault-tolerant flight controller design method is developed based on the online estimation of an eventual fault and the addition of a new control law to the normal control law in order to reduce the fault effect on the system without the need for a fault detection and isolation (FDI) mechanism. In the framework of LMI approach, the normal tracking performance of the resultant closed-loop system is optimized without any conservativeness and the states of fault modes asymptotically track those of the normal mode. A numerical example of an F-16 aircraft model and its simulation results are given
