Abstract: This paper investigates the problem of fault-tolerant control against sensor failures for a class of uncertain networked control system with random time delays. A novel fault-tolerant control scheme against sensor faults with consideration of both time delays and norm-bounded uncertainties is proposed to stabilise the target fault system. A complete fault model of sensors is developed with the objective to represent the type and degree of sensor faults in an integrated parameterised way in plant model. By employing multiple parameter-dependent Lyapunov-Krasovskii functions, sufficient conditions of system stabilisation and robust fault mode dependent controllers are derived. The simulation results show the effectiveness of the proposed method.
