This paper studies the problem of fuzzy adaptive secure tracking control for nonstrict-feedback nonlinear systems with unknown false data injection (FDI) attacks and input quantization. In the nonstrict-feedback nonlinear systems, the nonlinear functions contain all state variables so that the existing...
An adaptive resilient control is concerned for a class of cyber-physical systems (CPSs) in the presence of stealthy false data injection attacks in sensor networks and strict-feedback nonlinear dynamics. As the sensors are attacked by ill-disposed hackers, the exactly measured state information is...
1, where the sensor detects information of target and transmits the data to their neighbor sensors by wireless communication. In addition, the wireless communication channels between sensors are vulnerable to false data injection attack which aims to destroy the integrity of important data. The ...
A resilient control strategy is developed against false data injection attacks via attack estimation and compensation. The rest of the paper is organized as follows. InRelated workssection, the related works are studied. InHigh-order nonlinear MASsection, the high-order nonlinear MAS is presented in...
We address the problem of state estimation, attack isolation, and control of discrete-time linear time-invariant sys- tems under (potentially unbounded) actuator and sensor false data injection attacks. Using a bank of unknown input observers, each observer leading to an exponentially stable estimatio...

Specifically, we consider false data injection attacks modeled as: $$\begin{array}{c}{\stackrel{\sim}{x}}_{i}\left(t\right)={x}_{i}\left(t\right)+{a}_{i}\left(t\right)\end{array}$$ (30) where \({a}_{i}\left(t\right)\) is the attack signal injected by the ...

Deception attacks, such as false data injection attacks [6] and replay attacks [7], mainly tamper with transmitted data [8] to break data integrity. DoS attacks mainly block communication channels [9] to restrict communication between system components. Recently, some resilient or non-fragile ...
