摘要

研究了具有时延的网络控制系统在乘性虚假数据注入攻击下的最优跟踪性能（OTP）。提出了一种辅助模型，通过补充加性处理来保持受攻击信道输出的第一和第二矩的影响。采用二自由度控制（TDOF）方法和频域分析方法，推导了ncs的OTP显示表达式。结果表明，OTP与被测对象的固有特性、时延、乘法假数据的统计特性有密切的关系。最后，通过数值算例验证了计算结果。

Optimal tracking performance of networked control systems with time delay under multiplicative false data injection attacks

This paper investigates the optimal tracking performance (OTP) of networked control systems (NCSs) with time delay subjected to multiplicative false data injection (FDI) attacks. An auxiliary model is proposed to preserve the influences of the first and second moments of the attacked channel output through a supplementary additive process. By employing a two-degree-of-freedom control (TDOF) scheme and a frequency-domain analysis approach, a display expression for the OTP of NCSs is derived. It is shown that the OTP has a close relation with the intrinsic characteristic of the plant, time delay, and statistical characteristics of multiplicative false data. Finally, a numerical example is provided to validate the results.

期刊介绍： Founded in 1981 by two of the pre-eminent control theorists, Roger Brockett and Jan Willems, Systems & Control Letters is one of the leading journals in the field of control theory. The aim of the journal is to allow dissemination of relatively concise but highly original contributions whose high initial quality enables a relatively rapid review process. All aspects of the fields of systems and control are covered, especially mathematically-oriented and theoretical papers that have a clear relevance to engineering, physical and biological sciences, and even economics. Application-oriented papers with sophisticated and rigorous mathematical elements are also welcome.
