Fault-tolerant Control for MIMO Networked Control Systems with Uncertainties

The considered networked control system are multiple-input-multiple-output (MIMO) with uncertainties. The sensors and controllers are time-driven, some of the sensors fail to transfer data to the controller because of the network bandwidth limit. The networked control system with sensor faults is modelled as a discrete model with system uncertainties. Using Lyapunov method, a sufficient condition for the stability is given in terms of linear matrix inequalities (LMIs). Based on the solutions of these LMIs, the law of the controller based on observer is given. A numeral example is illustrated to validate the method
