Abstract
In this brief, we investigate the Cyber-Physical Systems (CPSs) with measurement channels under Denial-of-Service (DoS) attacks. An equivalent predictive control system model and attack model are constructed firstly. To compensate for the data loss due to the attacks, the predictive controller is designed based on linear quadratic form. Furthermore, through the design of an observer-based output predictor, a novel resilient observer-based predictive control framework is presented to improve the robustness of the LQ controller. By constructing the closed-loop system with proposed controller, the states of the control system are theoretically proved to be asymptotically stable under the influence of DoS attacks. Finally, the efficacy of the proposed control strategy is illustrated through a comparative simulation example.
