Abstract:
The problem of designing a decentralized guaranteed cost satisfactory fault-tolerant control scheme for a class of discrete large scale interconnected systems with norm-bounded time-varying parameter uncertainties under a class of actuator failures is discussed.Based on a more general and practical model of continuous actuator gain failures,sufficient conditions for the existence of the decentralized controllers are derived,and a parameterized characterization of a set of decentralized guaranteed cost satisfactory fault-tolerant controllers is provided.Furthermore,a convex optimization problem is formulated to select the optimal decentralized guaranteed cost satisfactory fault-tolerant controller which minimizes the upper bound of the closed loop cost function.A simulation example shows the effectiveness of the proposed method.
