摘要
当攻击者成功实施恶意攻击时,集成系统中的嵌入式闭环可能会遭到破坏。因此,在过去的十年中,人们对提高网络物理系统(CPS)安全性的兴趣与日俱增。本文研究了在拒绝服务(DoS)情况下,具有众多传输通道的 CPS 的弹性控制问题。首先,针对多通道 DoS(MCDoS)条件开发了部分观测器技术。其次,在保持闭环系统输入到状态稳定性(ISS)的同时,对 MCDoS 的变化频率进行了描述。接下来,开发了一种基于事件的控制策略,以应对全规模 DoS (FSDoS)。最后,设计出最佳控制参数,使系统能够抵御最大 MCDoS 变化频率。
Characterization of multi-channel denial-of-service
The embedded closed-loop in integrated systems can be compromised when attackers execute a successful malicious attack. Hence, over the past decade, interest in enhancing the safety of Cyber-Physical Systems (CPSs) has risen. This article examines the resilient control problem for CPSs with numerous transmission channels under Denial-of-Service (DoS). To begin with, a partial observer technique is developed in response to the Multi-Channel DoS (MCDoS) condition. Secondly, the changing frequency of MCDoS is characterized while maintaining the Input-to-State Stability (ISS) of the closed-loop system. Next, an event-based control strategy is developed to address Full-Scale DoS (FSDoS). Finally, the optimal control parameters are designed to make the system resilient against maximum MCDoS changing frequency.
期刊介绍:
The European Control Association (EUCA) has among its objectives to promote the development of the discipline. Apart from the European Control Conferences, the European Journal of Control is the Association''s main channel for the dissemination of important contributions in the field.
The aim of the Journal is to publish high quality papers on the theory and practice of control and systems engineering.
The scope of the Journal will be wide and cover all aspects of the discipline including methodologies, techniques and applications.
Research in control and systems engineering is necessary to develop new concepts and tools which enhance our understanding and improve our ability to design and implement high performance control systems. Submitted papers should stress the practical motivations and relevance of their results.
The design and implementation of a successful control system requires the use of a range of techniques:
Modelling
Robustness Analysis
Identification
Optimization
Control Law Design
Numerical analysis
Fault Detection, and so on.
