Abstract

This paper studies the security control of direct current (DC) microgrids under deception attacks, and a dynamic event-triggered mechanism (DETM) is proposed to save constrained network bandwidth. The DETM can reduce the frequency of data communications and exclude Zeno behavior inherently. Then, a time-delay closed-loop system model is built, which integrates parameters of the DC microgrid, the DETM, deception attacks, injection current controller, and network-induced delays in one unified framework. Sufficient conditions are derived for globally exponentially ultimately bounded stability in mean square, which establish the relationship between system performance and the contributing factors such as the DETM, deception attacks, and network delays. Further, a co-design method is presented to derive the parameters of the controller and the DETM in just one step. Simulation results confirm the effectiveness of the proposed method for security control of DC microgrids, achieving 21.5% savings of communication resources while effectively stabilizing the system even 10.7% of the transmitted data that are manipulated by the deception attacks.

欺骗攻击下直流微电网的安全控制--一种动态事件触发方法

本文研究了欺骗攻击下直流（DC）微电网的安全控制，并提出了一种动态事件触发机制（DETM），以节省受限的网络带宽。DETM 可以降低数据通信频率，从本质上排除 Zeno 行为。然后，建立了一个时延闭环系统模型，将直流微电网参数、DETM、欺骗攻击、注入电流控制器和网络引起的时延整合在一个统一的框架中。推导出了均方值全局指数终极约束稳定性的充分条件，建立了系统性能与 DETM、欺骗攻击和网络延迟等促成因素之间的关系。此外，还提出了一种协同设计方法，只需一步即可得出控制器和 DETM 的参数。仿真结果证实了所提方法在直流微电网安全控制方面的有效性，在有效稳定系统的同时节省了 21.5% 的通信资源，即使 10.7% 的传输数据被欺骗攻击所操纵。

期刊介绍： The Asian Journal of Control, an Asian Control Association (ACA) and Chinese Automatic Control Society (CACS) affiliated journal, is the first international journal originating from the Asia Pacific region. The Asian Journal of Control publishes papers on original theoretical and practical research and developments in the areas of control, involving all facets of control theory and its application. Published six times a year, the Journal aims to be a key platform for control communities throughout the world. The Journal provides a forum where control researchers and practitioners can exchange knowledge and experiences on the latest advances in the control areas, and plays an educational role for students and experienced researchers in other disciplines interested in this continually growing field. The scope of the journal is extensive. Topics include: The theory and design of control systems and components, encompassing: Robust and distributed control using geometric, optimal, stochastic and nonlinear methods Game theory and state estimation Adaptive control, including neural networks, learning, parameter estimation and system fault detection Artificial intelligence, fuzzy and expert systems Hierarchical and man-machine systems All parts of systems engineering which consider the reliability of components and systems Emerging application areas, such as: Robotics Mechatronics Computers for computer-aided design, manufacturing, and control of various industrial processes Space vehicles and aircraft, ships, and traffic Biomedical systems National economies Power systems Agriculture Natural resources.
