Abstract

This study explores the design of controllers for interval type-2 (IT2) fuzzy time-delay networked systems that are vulnerable to various cyber attacks, including denial-of-service (DoS) and deception attacks. To enhance resource utilization, a dynamic event-triggered mechanism (DETM) is utilized for signal transmission. This mechanism is designed to optimize the timing of data exchanges and reduce unnecessary communication. A Lyapunov-Krasovskii functional (LKF) is introduced to investigate the stability of the system under these challenging conditions. Exponential stability and the

H_{\infty}

performance index are incorporated into stability conditions, based on which the control law is established. The effectiveness of the proposed control strategy and the DETM is demonstrated through two illustrative examples. It is shown that the approach maintains the stability in the presence of DoS and deception attacks, confirming the practical applicability of the proposed method. This comprehensive analysis and verification highlight the potential applications of the proposed design in attack scenarios.

混合网络攻击下模糊时滞系统的动态事件触发控制

本研究探讨区间型2 （IT2）模糊时滞网络系统的控制器设计，该系统容易受到各种网络攻击，包括拒绝服务（DoS）和欺骗攻击。为了提高资源利用率，采用动态事件触发机制（DETM）进行信号传输。该机制旨在优化数据交换的时间，减少不必要的通信。引入Lyapunov-Krasovskii泛函（LKF）来研究系统在这些具有挑战性的条件下的稳定性。将指数稳定性和H∞性能指标纳入稳定条件，在此基础上建立控制律。通过两个实例验证了所提出的控制策略和DETM的有效性。结果表明，该方法在DoS攻击和欺骗攻击下仍能保持稳定性，验证了该方法的实用性。这种全面的分析和验证突出了所提出的设计在攻击场景中的潜在应用。
