Abstract
With the widespread application of communication networks in industrial control systems, cyber-attacks bring a huge threat to the networked control system. In this paper, the issue of secure control of nonlinear jump networked systems with false data inject (FDI) attacks is investigated. In order to against the malicious attacks, a reduced-order-asynchronous sliding-mode control (SMC) strategy is proposed. Firstly, in order to damp the effect of nonlinear term and FDI attacks, an asynchronous sliding-mode function is designed, and the resultant sliding-mode dynamics is generated by using the reduced-order method. Then, the stability conditions for the reduced-order sliding-mode dynamics are given, and the sliding-mode parameters are solved by linear matrix inequality technology. Furthermore, the sliding-mode controllers are designed under the situation of the parameters is known or unknown, respectively, and the reachability of the sliding-mode motion is certificated. Finally, two examples are implemented to illustrate the potential of the presented control strategy.
