Abstract :
In this paper, three decentralized output feedback fault-tolerant control methods of design integrity with actor failures, sensor failures and mixed failures are presented for uncertain interconnected large-scale systems. Not only can they make the faulty closed large-scale systems asymptotically stable under the uncertain bounded parameters, but also assure the H∞ properties are optimal or suboptimal. The example simulations demonstrate that the methods are effective
