Abstract:Together with the rapid developments of automation control, computer science, and communication technology, networked control systems (NCSs) have been widely applied in many fields such as industrial control, aeronautics and astronautics, and Internet of things. Firstly, aiming at the discrete NCSs with actuator saturation and faults, a fault tolerant controller is designed by considering the network-induced delay and parameter uncertainty; secondly, by using Lyapunov stability theory and the information of upper bound of delay, a kind of functional is constructed and more tightly upper bound is obtained by utilizing Jenson inequality technique; thirdly, some asymptotical criteria are obtained and controller gain can be solved in the frame of LMI(linear matrix inequality) forms; finally, the simulations show the effectiveness and less conservativeness of the proposed method.
