摘要

This paper focuses on addressing the impacts of denial of service (DoS) attacks on vehicle suspension systems through the novel application of integral event-triggering control (IETC). The proposed approach models a networked suspension system, considering realistic scenarios involving network-induced delays and aperiodic DoS attack intervals. Rather than the periodic signals, the aperiodic jamming signals which are more realistic in nature are represented by means of switched system which encloses the attack and sleeping intervals. Unlike traditional Event-Triggering Control (ETC), the IETC framework incorporates integral action in the triggering condition, effectively mitigating steady-state errors and avoiding Zeno behavior. Stability and performance guarantees are established using Lyapunov theory, with the control gains derived through linear matrix inequalities (LMIs). Numerical simulations compare the performance of the proposed IETC with conventional ETC under random and sinusoidal road disturbances, demonstrating its robustness and superiority in ensuring ride comfort, suspension deflection, and road holding.
