“…As for attack-resilient control, the papers [2], [32], [33] are devoted to studying deception attacks, where attackers intentionally modify measurements and control commands. Denial-of-service (DoS) attacks destroy the data availability in control systems and are tackled in recent papers [1], [3], [4], [9]. More specifically, the papers [1], [9] formulate finite-horizon LQG control problems as dynamic zero-sum games between the controller and the jammer.…”

“…More specifically, the papers [1], [9] formulate finite-horizon LQG control problems as dynamic zero-sum games between the controller and the jammer. In [3], the authors investigate the security independency in infinite-horizon LQG against DoS attacks, and fully characterize the equilibrium of the induced game. In our paper [35], a distributed receding-horizon control law is proposed to ensure that vehicles reach the desired formation despite the DoS and replay attacks.…”

This paper studies a resilient control problem for discrete-time, linear time-invariant systems subject to state and input constraints. State measurements and control commands are transmitted over a communication network and could be corrupted by adversaries. In particular, we consider the replay attackers who maliciously repeat the messages sent from the operator to the actuator. We propose a variation of the receding-horizon control law to deal with the replay attacks and analyze the resulting system performance degradation. A class of competitive (resp. cooperative) resource allocation problems for resilient networked control systems is also investigated.

Abstract. Based on frequency-domain transformation technique, this paper proposes an attack detection scheme for stochastic control systems under stochastic cyber-attacks and disturbances. The focus is on designing an anomaly detector for the stochastic control systems. First, we construct a model of stochastic control system with stochastic cyber-attacks which satisfy the Markovian stochastic process. And we also introduced the stochastic attack models that a control system is possibly exposed to. Next, based on the frequency-domain transformation technique and linear algebra theory, we propose an algebraic detection scheme for a possible stochastic cyber-attack. We transform the detector error dynamic equation into an algebraic equation. By analyzing the rank of the stochastic matrix E (Q(z 0 )) in the algebraic equation, residual information is obtained and anomalies in the stochastic system are detected. In addition, sufficient and necessary conditions guaranteeing the detectability of the stochastic cyber-attacks are obtained. The presented detection approach in this paper is simple, straightforward and more ease to implement. Finally, the results are applied to some physical systems that are respectively subject to a stochastic data denial-of-service (DoS) attack and a stochastic data deception attack on the actuator. The simulation results underline that the detection approach is efficient and feasible in practical application.

Networked control systems (NCSs) are spatially distributed systems in which the sensors, actuators, and controllers are connected through a shared communication network. The advantages of the network architectures include reduced system wiring, plug and play devices, increased system agility, and ease of system diagnosis and maintenance. Meanwhile, the presence of a communication network in a control loop induces many imperfections. Therefore, the analysis and synthesis of NCSs have received considerable attention in the last two decades. In this article, we review fundamental communication imperfections in NCSs and the main approaches to the modeling of NCSs. Then, recent results on time‐delay approach to event‐triggered control are recalled. The article highlights time‐delay approach developed to modeling, analysis and synthesis of NCSs, under communication constraints, with a particular focus on Round‐Robin, Try‐once‐discard, and stochastic protocols. The time‐delay approach allows communication delays to be larger than the sampling intervals in the presence of scheduling protocols. Moreover, some results on networked control of distributed parameter systems are introduced. Finally, some open problems are briefly addressed.
