摘要

研究了网络攻击下具有不确定干扰的高阶非线性多智能体系统的隐私保护自适应模糊分布式优化问题,其中考虑了DoS和窃听攻击。为了在分布式优化设计和模糊跟踪控制之间架起一座桥梁,提出了实现最优目标的层次结构。在设计防御DoS攻击的分布式优化算法时,构造一个视觉信号,保证agent协同最小化目标函数。采用了基于SingleMod密码系统的隐私保护策略,避免了外部窃听者造成的隐私泄露。然后,利用模糊逻辑系统和自适应反演技术,设计了一种自适应模糊控制器,保证质量输出收敛到最优解。最后,通过仿真算例验证了所得结果的有效性。

Adaptive fuzzy-based distributed optimization with privacy protection for uncertain high-order nonlinear multi-agent systems against two types of cyber attacks
This paper investigates the adaptive fuzzy distributed optimization with privacy protection for high-order nonlinear multi-agent systems (MASs) with uncertain disturbance under cyber attacks, in which DoS and eavesdropping attacks are considered. A hierarchical architecture for achieving an optimal objective is provided to build a bridge between distributed optimization design and fuzzy tracking control. A visual signal is constructed to ensure the agents cooperatively minimize the objective function when designing a distributed optimization algorithm to defend against DoS attacks. Moreover, the SingleMod cryptosystem-based privacy protection strategy is employed to avoid privacy leakage caused by external eavesdroppers. Then, an adaptive fuzzy controller is developed to guarantee that the output of MASs can converge to the optimal solution by utilizing a fuzzy logic system and adaptive backstepping technique. Finally, a simulation example is provided to illustrate the validity of the obtained results.
