研究了线性时不变奇异摄动系统针对传感器故障的H/SUB/SPL可靠控制问题。通过时间尺度分解，将全阶系统分解为慢子系统和快子系统。在为全局系统设计了可靠的H/SUB/SPL INFIN//控制器后，通过对代数Riccati方程的处理，得到了基于慢速和快速性问题的两个降低可靠性的H/SUB/SPL INFIN//子控制器。所得到的控制系统是可靠的，因为当所有控制部件运行时以及当传感器发生故障时，它们提供保证的渐近稳定性和H/SUB/SPL//性能。
This paper studies the reliable H/sub /spl infin// control for linear time-invariant singularly perturbed systems against sensor failures. By time-scale decomposition, the full-order system is decomposed into slow and fast subsystems. After designing a reliable H/sub /spl infin// controller for the global system, two reduced reliable H/sub /spl infin// sub-controllers based on the slow and fast problems are obtained through the manipulation of the algebraic Riccati equations. The resulting control systems are reliable in that they provide guaranteed asymptotic stability and H/sub /spl infin// performance when all control components are operational as well as when sensor failures occur.
