“…By solving the matrix equation (18), we have appropriate parameter , ,  for observer (19). We assume that the sensor attacks to subsystems 2 and 4 occur in time periods of (5,8) and (13,16), respectively, and subsystems 1 and 3 are without sensor attack. That is we assume that f s 1…”

“…Compared with the physical layer, the cyber layer is much more susceptible to be attacked on the communication channels, thus how to protect the cyber layer from being attacked becomes one of the major considerations for the researchers, especially in some crucial fields such as smart grid system and nuclear power system, and many significant results have been obtained. Kwon and Hwang pointed out that cyber attack has become one of the major threats to CPSs due to their close integration of logical and physical processes.…”

Summary This article investigates the sensor attack detection and isolation problems for cyber‐physical systems under attacked situation. To begin with, an overall system is constructed for the network of dynamic system and all the issues are dealt with for the overall system instead of every subsystem. Then, we prove that the preconditions which are made on the original subsystem can be transferred on to the overall system. After this, for the overall system, a sliding mode observer that is robust to the disturbance but sensitive to the sensor attack is designed as sensor attack detector to issue an alarm when at least one subsystem is attacked. In addition, we cope with the sensor fault isolation problem by building an augmented descriptor system for the overall system and we further prove that the precondition can be kept for the augmented descriptor system. Then, another robust sliding mode observer is designed to reach the goal of attack isolation. Finally, a simulation example is given to verify the effectiveness of the proposed methods.

“…Embora CPS apresentem maior eficiência, eles se tornam mais suscetíveis a ataques envolvendo o domínio cibernético, conhecidos como Ciber-Ataques (Sandberg et al, 2015). Conforme apresentado em (Pasqualetti et al, 2013), prejuízos significativos podem ser causados por ciber-ataques sobre os canais de comunicação ou de dados, como por exemplo a falha no sistema de tratamento de esgoto (Slay and Miller, 2007), o acidente na planta nuclear de Taiwan (Lee et al, 2010), os apagões de energia no Brasil (Conti, 2010) e o vírus Stuxnet (Langner, 2011). Tais casos elucidaram como os mecanismos de segurança adotados precisavam ser complementados por estratégias de controle capazes de detectar e rejeitar esses ataques.…”

Neste artigo, o problema de monitoramento e reconstrução de ciber-ataques em sistemas ciber-físicos lineares multivariáveis incertos é estudado. A classe de ataques cibernéticos considerada neste trabalho é capaz de corromper os estados ou as saídas da planta. Usando técnicas de modos deslizantes de ordem superior, um monitor de ataques multivariável é proposto para detecção e reconstrução dos ataques. Além disso, o uso de Filtros de Aproximação de Primeira Ordem garantem resultados globais de estabilidade e convergência. O problema de rejeição de ataques em plantas quadradas é abordado com o uso de técnicas de modo deslizante, garantindo rastreamento da saída em tempo finito enquanto rejeita os efeitos do ciber-ataque.
