摘要
对于存在不匹配参数不确定性的非线性多代理系统,通过反步进设计实现具有输入量化和欺骗攻击的分布式共识跟踪控制存在技术难度。由于 i) 系统包含不匹配的不确定性;ii) 攻击后输出不可用,使得使用传统误差面的传统递归控制设计策略变得不适用;iii) 由于只有受损的输出信号可用,与未知攻击权重相关的非线性项的影响难以在现有的输出反馈控制结果中明确解决。在本文中,我们提出了一种规避这些障碍的解决方案,即仅使用受损输出构建一组新的 K 滤波器,再加上涉及受攻击输出和滤波器变量的坐标变换,从而开发出一种新形式的基于反步法的分布式弹性自适应控制协议。同时,在实际控制器中加入了额外的补偿项,以处理量化对系统稳定性的影响。研究表明,通过适当选择 Lyapunov 函数,可以实现所有闭环信号的全局均匀有界性和渐近输出共识跟踪。我们还提供了一个实践案例来验证我们方案的优势。
Distributed resilient adaptive consensus tracking control of nonlinear multi-agent systems dealing with deception attacks via K-filters approach
It poses technical difficulty to achieve distributed consensus tracking control with input quantizations and deception attacks for nonlinear multi-agent systems subject to mismatched parametric uncertainties via backstepping design. The underlying problem becomes even more complicated because i) the system contains mismatched uncertainties; ii) the output becomes unavailable after attacks, making the conventional recursive control design strategy using traditional error surfaces unsuitable; iii) since only the compromised output signal is available, the impacts of nonlinear items related to unknown attack weights become difficult to be explicitly addressed in the existing available output feedback control results. In this paper, we present a solution to circumvent these obstacles by constructing a set of new K-filters using compromised output only, which, together with a coordinate transformation involving the attacked output and filter variables, allow a new form of backstepping based distributed resilient adaptive control protocol to be developed. Meanwhile, an extra compensation term is incorporated into the real controller to handle the effect of quantization on the system stability. It is shown that, with proper choices of Lyapunov functions, the global uniform boundedness of all the closed-loop signals and the asymptotically output consensus tracking can be achieved. A practice example is provided to verify the benefits of our scheme.
期刊介绍:
Automatica is a leading archival publication in the field of systems and control. The field encompasses today a broad set of areas and topics, and is thriving not only within itself but also in terms of its impact on other fields, such as communications, computers, biology, energy and economics. Since its inception in 1963, Automatica has kept abreast with the evolution of the field over the years, and has emerged as a leading publication driving the trends in the field.
After being founded in 1963, Automatica became a journal of the International Federation of Automatic Control (IFAC) in 1969. It features a characteristic blend of theoretical and applied papers of archival, lasting value, reporting cutting edge research results by authors across the globe. It features articles in distinct categories, including regular, brief and survey papers, technical communiqués, correspondence items, as well as reviews on published books of interest to the readership. It occasionally publishes special issues on emerging new topics or established mature topics of interest to a broad audience.
Automatica solicits original high-quality contributions in all the categories listed above, and in all areas of systems and control interpreted in a broad sense and evolving constantly. They may be submitted directly to a subject editor or to the Editor-in-Chief if not sure about the subject area. Editorial procedures in place assure careful, fair, and prompt handling of all submitted articles. Accepted papers appear in the journal in the shortest time feasible given production time constraints.
