ROBUST FAULT-TOLERANT CONTROL AND DESIGN FOR UNCERTAIN LINEAR SYSTEMS

研究含结构参数扰动的不确定线性系统的鲁棒容错控制问题，即设计反馈控制器，使闭环系统对可允的参数扰动具有鲁棒性，同时对执行器或传感器失效具有完整性。基于修正的代数矩阵方程，给出了期望的鲁棒容错控制器的存在条件及其显式表示。

The problem of robust fault-tolerant control for uncertain linear systems with structured parameter perturbation is studied. The purpose is to design the feedback controllers such that the closed-loop systems possess robustness for the case of parameter perturbations,and possess integrity for the case of actuator or sensor failures. Based on a modified algebra matrix equation,this paper provides the conditions for the existence of the desired robust fault-tolerant controllers. An explicit expression of the desired controllers is also presented. A design example is used to demonstrate the directness and simplicity of the present design method.
