Abstract

This paper concerns the problem of an observer-based memory-event-triggered controller for quarter-vehicle suspension systems (SSs) under deception attacks. The observer-based controller is utilized to solve the difficulty that full state information of quarter-vehicle SSs cannot be obtained. A memory-event-triggered mechanism (METM) considering both network load and observer performance is proposed, where the historical information of the measured output is utilized in the event-triggered condition and the observer, reducing mal-triggering events caused by abrupt disturbance and enhancing the sensitivity to deception attacks. Sufficient conditions that guarantees an H $$ {H}_{\infty } $$ performance of quarter-vehicle SSs are presented. Finally, a simulation example under the bump road conditions is provided to validate the effectiveness of the derived controller.
