一种基于DOS攻击观测器的区间二型T-S模糊系统的安全控制方法

An Internal Type-2 T-S Fuzzy Based on DOS Attacks Observer System with a Security Control Method

摘要: 本文重点讨论了在DOS攻击下，具有分布式延迟的区间类型-2 (IT2)T-S模糊离散时间系统的抗异常值观察器和控制器。DOS攻击发生在传感器通道和观测器通道之间。为了解释随机发生的DOS攻击对控制结构的影响，构建了一个安全性能的新指导。参数不确定性和DOS攻击的随机事件通过两组具有概率分布的伯努利随机变量进行控制。构建了一个抗异常值的基于观察器的安全控制(OBSC)，以诱导创新的饱和结构，从而减轻对DOS进攻的估计方面的消极影响。该方案的目标是设计一个OBSC，在实现理想的安全水平的同时，能够保证估计误差的有界性。最终，提出了一个数值模拟样本来证明上述控制项目的实用性和有效性。

Abstract: This article focuses on the outlier-resistant observer-based controller for the interval type-2 (IT2) T-S fuzzy discrete-time systems with distributed delays under DOS attacks. The DOS attack takes place between sensor channel and observer channel. A neoteric guidance for safety performance is constructed to explain the randomly happening DOS offensive on the control structure. The random events of parameter uncertainty and DOS offensives are controlled via two sets of Bernoulli stochas-tic variables with foregone probability distributions. One outlier-resistant observer-based security control (OBSC) is constructed to induce an innovation saturation structure so as to alleviate the pas-sive influence on the DOS offensives about the estimation aspect. The goal of the solution is to design an OBSC that can ensure boundedness in estimation error while achieving the ideal level of safety. Ultimately, a quantitative value simulation sample is put forward to justify the practicality and va-lidity of the above-mentioned control project.
