研究了一类网络化Takagi-Sugeno（T-S）模糊系统在欺骗攻击下的自适应环面事件控制问题.由于网络固有的开放性，网络化T-S模糊系统中不可避免的欺骗攻击总是随机出现的。欺骗攻击的发生成功地描述了使用一个二元随机变量与已知的统计特性。在所考虑的自适应torus-event-based通信机制下，构造模糊控制器，保证网络化T-S模糊系统在欺骗攻击下的渐近均方稳定性（AMSS）和指标.为了设计所需的模糊控制器，网络T-S模糊系统的统一框架，首先建立通过自适应环面事件为基础的通信机制，欺骗攻击的数学模型，和异步前提技术。利用扩展的李雅普诺夫函数，充分条件同时获得解决AMSS和闭环控制系统的干扰抑制问题。随后，通过线性矩阵不等式计算基于自适应环面事件的模糊控制器增益。最后，通过隧道电路系统的仿真实例验证了该控制机制的有效性和可靠性。
This article addresses the adaptive torus‐event‐based control problem for a class of networked Takagi‐Sugeno (T‐S) fuzzy systems under deception attacks. Due to the inherent openness of the network, the inevitable deception attacks in the networked T‐S fuzzy systems always appear randomly. The occurrence of deception attacks is successfully described by using a binary stochastic variable with known statistical characteristics. Under the considered adaptive torus‐event‐based communication mechanism, fuzzy controllers are constructed to guarantee the asymptotically mean‐square stability (AMSS) and the index of the networked T‐S fuzzy systems under deception attacks. To design the desired fuzzy controllers, a unified framework of the networked T‐S fuzzy systems is first established via the adaptive torus‐event‐based communication mechanism, the mathematical model of deception attacks, and the asynchronous premise technology. By utilizing the extended Lyapunov function, the sufficient conditions are simultaneously derived to address the AMSS and the disturbance suppression issues of closed‐loop control systems. Subsequently, the adaptive torus‐event‐based fuzzy controller gains are calculated via linear matrix inequalities. Finally, a simulation example concerning the tunnel circuit system is established to verify the availability and reliability of the proposed control mechanism.
