基于渐近调节的容错控制

针对线性动态故障系统，提出了一种基于线性二次型问题的容错控制方法，该方法可以通过牛顿一拉普森迭代算法来渐近调节状态反馈控制律，以降低故障系统由于故障诊断和系统重构的延时所产生的运行风险，从而提高系统性能。给出了适用该方法的充分条件，并进一步讨论了该方法在系统能耗方面的优越性，对一个具体航空系统进行了仿真，结果证实了该渐近方法的有效性。

Fault Tolerant Control Based on Progressive Accommodation

A fault tolerant control(FTC) strategy based on the linear quadratic(LQ) problem is proposed for linear dynamic system.The strategy progressively accommodates the feedback control law according to the iteration solutions of the Newton-Raphson method,it can reduce the risk of the system performance effectively,which results from the time delay of fault detection and isolation(FDI) and fault accommodation(FA).The sufficient condition of the algorithm is presented and the problem of system cost is also discussed.An aircraft example shows the efficiency of the proposed method.
