Abstract :
The problem of decentralized robust fault-tolerant control is considered for a class of uncertain large-scale interconnected systems possessing integrity in the paper. A sufficient condition is proposed for the class system possessing integrity and robustness against sensor failures, structural reconfigurations and parameter uncertainties by using the vector Lyapunov function approach and the linear matrix inequality (LMI) approach. The effectiveness and feasibleness of this method are demonstrated with a simulation example.
