Abstract

This paper proposed a novel robust controller to ensure the security and stability for a class of cyber-physical systems subject to the effects including actuator attacks, external disturbances, and encoder/decoder mismatches. An optimized H2 performance in the form of linear matrix inequality solved the linear gain of the constructed controller. The nonlinear structure of the control included two parts: one aimed to eliminate the influence of external disturbance and quantization error, and the other part compensated the actuator attack by means of adaptive estimations of unknown actuator attack parameters. Finally, the simulation results show that the controller guarantees uniform ultimate boundedness of the closed-loop dynamical system, which shows the effectiveness of the proposed method.
