不确定离散系统的鲁棒容错H_∞控制

Robust Fault-tolerant H_∞ Control for Uncertain Discrete Systems

针对一类范数有界参数不确定性离散系统,研究了该系统的鲁棒容错H∞控制问题.运用矢量不等式方法,给出了在传感器和执行器发生故障时,不确定离散系统鲁棒稳定并满足一定性能要求的鲁棒容错H∞控制律的设计方法,得到了鲁棒容错H∞状态反馈控制律的存在条件及其代数表达形式.

For a class of discrete systems with norm-bounded parameter uncertainties, the robust fault-tolerant H∞ control problem is studied. By using vector inequality, the authors provide the design methods of robust fault - tolerant H∞ control laws which ensure the systems robust stabilization and satisfy some performance, and also obtain the existent condition of the robust fault - tolerant H∞ controller by state feedback and its algebra expression.
