摘　　要：本文研究具有完整性的状态反馈控制系统的设计方法，主要由两部分构成．第一部分考虑对任一传感器失效具有完整性且满足预先给定的H∞干扰衰减指标约束的控制系统综合设计问题，利用代数Riccati方程方法，给出了该问题的解。第二部分则研究使闭环系统对传感器失效具有完整性的状态反馈控制的存在条件，并给出其显式表示及具体设计步骤，数值例子说明了本文设计方法的有效性与直接性。In this paper,the design approaches to state feedback control systems possessing integrity are studied. This paper consists of two parts. In the first part,the problem of designing state feedback control sys-tems,which possess integrity against arbitrary a sensor failure and meet the specified H∞ disturbance attenua-tion constraint,is considered. The problem is solved by using the algebraic Riccati equation approach. In the second part,the conditions for the existence of state feedback controllers which possess integrity against sen-sor failures are studied. The explicit expression and direct design method of desired controllers are also given.Two numerical examples are presented to show the effectiveness of the proposed design approaches.
