摘要

线性二次(LQ)问题在控制设计中非常流行。本文针对执行机构可能发生故障的情况，分析了LQ问题。结果表明，容错只有在考虑可容许解(而不是最优解)时才能定义。给出了故障容错和系统重构策略的可能容错条件。

Actuator faults and the linear quadratic control problem

Linear quadratic (LQ) problems are very popular for control design. In this paper, the LQ problem is analyzed with respect to the possible occurrence of actuator faults. It is shown that fault tolerance can only be defined when admissible (instead of optimal) solutions are considered. Conditions for a fault to be possibly tolerated are given both for the fault accommodation and for the system reconfiguration strategies.
