Robust Fault Tolerant Control for Networked Control Systems with Uncertain Delay
The problem of robust fault-tolerant control for networked control systems (NCSs) is discussed in this paper. The uncertainty of network-induced delays is converted to the uncertainty of the parameter matrix, and the states are transformed into the augmented states to eliminate the effect of the asynchronism. Based on Lyapunov stability theory and linear matrix inequality (LMI), the sufficient conditions for closed-loop networked control systems possessing robust integrity against sensor or actuator failures are given by adopting memoryless state feedback control law, and the robust fault-tolerant controller is designed via solving several linear matrix inequalities. Finally, numerical example is given to demonstrate effectiveness and feasibility of the proposed approach.
