具有完整性的容错控制系统设计：离散时间情形

该文研究了具有完整性的离散时间容错控制系统设计问题，即设计状态反馈控制器，使闭环系统对可能的传感器失效仍保持渐近稳定。基于一修正的代数高散Ｒｉｃｃａｔｉ方程，该文直接证明了怕容错控制器的存在性，并异出其解析表达式，提供了具体的控制设计步骤。

Design of Fault tolerant Control Systems Possessing Integrity The Discrete time Case

In this paper,the design of fault tolerant discrete time control systems possessing integrity is studied.A state feedback controller is designed with the resulting closed loop system remaining stable against possible complete or partial sensor failures.The proof for the existence of desired fault tolerant controllers is made based on a modified algebraic discrete Riccati equation,while the analytical expression of these controllers is also derived.Then,the straightforward design steps of fault tolerant controllers are given.Finally,the main idea and advantage of the present design method are demonstrated by using a class of engineering control systems as an applied example.Compared with the existing results,the present approach is more direct and effective,and therefore possesses better prospect in engineering applications.
