摘要
讨论具有对称结构的广义大系统的Ｈ∞分散控制以及容错度问题，利用系统Ｈ∞分散控制 存在的充分条件，考虑当系统控制通道出现故障时，通过低维数的某些系统求闭环系统的 极点以及Ｈ∞范数，且能求出系统容错度．
The problems of H∞ decentralized control and the tolerance to actuator failure are studied for lange-scale symmetric composite descriptor systems. By exploit- ing a sufficient condition for the existence of a decentralized H∞. controller, for the nominal case as well as for contingent situations characterized by con- trol channel failures, the poles and the H∞ - norm of the closed-loop system can be calculated easily based on certain systems of reduced dimensions. Con- sequently, the tolerance to actuator failure can be easily tested.
