不确定时滞系统的鲁棒容错控制

Robust Fault-tolerant Control of Uncertain Linear Time-delay Systems

研究了一类不确定线性时滞系统的鲁棒容错控制问题,基于Lyapunov稳定性理论,证明了当采用一种带时滞的状态反馈控制律时,该系统对于传感器和执行器故障具有完整性,给出了闭环系统具有鲁棒容错能力的条件.

Robust fault-tolerant control of a kind of linear uncertain time-delay systems is studied. Based on Lyapunov asymptotic stability theory, when a kind of state-feedback controller with time-delay is applied, the system is proved to possess the integrity against sensor and actuator failures. The sufficient conditions for the closed-loop system to possess robustness in the presence of parameter uncertainties are given.
