Input-to-state stability of switched linear systems with unstabilizable modes under DoS attacks

This work studies the almost output tracking control problem via the co-design of controllers and a switching strategy for switched positive systems. For devising a hysteresis switching strategy, the nonnegative state space is divided into some subdomains, where each subdomain corresponds to an activated subsystem. The main advantage of the proposed methodology is that the switching frequency can be reduced in contrast to the min-switching based designs, and the almost output tracking control problem is allowed to be unsolvable for each subsystem. The almost output tracking criteria, based on multiple linear copositive Lyapunov functions are established in linear vector inequalities form, which ensures asymptotic convergence of the output tracking error to zero, the positivity as well as a prescribed L 1 -gain index in presence of disturbances. Finally, the theoretical findings are applied to the output tracking control of the boost converter circuit.

Almost output tracking control for switched positive systems: A hysteresis switching strategy

Wang

Zhang

Sang

et al. 2023

“…It is necessary to pay attention to the study on DoS attacks 16 . In Reference 17, an easily solvable condition was proposed for the admissible sampling interval and a less conservative result for the stability of NSS was obtained under sampling control with DoS attacks. In Reference 18, some new results on DoS attack duration/frequency constraints were given to ensure system stability.…”

Optimal security control for networked switched systems with a state‐prediction‐based anti‐DoS mechanism

Geng

Xing

et al. 2023

The openness of networks renders them vulnerable to various forms of attacks.When networked switched systems (NSS) suffer from denial of service (DoS) attacks and delays, the real-time property of the dataset decreases, greatly affecting the control performance. To address this issue, this article proposes a switched adaptive dynamic programming (ADP) predictive control method.An event-triggered mechanism is designed to reduce unnecessary waste of network transmission resources. A predictive mechanism is designed to accurately reconstruct the missing system state and switching signal under DoS network attacks. Then, the reconstructed data are applied to train the actor and critic neural networks, which are used to approximate the optimal control policy and performance index function (PIF) of the NSS, respectively. Furthermore, the iterative convergence of the switched ADP algorithm is proved. Finally, a numerical example is provided to verify the effectiveness of the proposed method.

“…So far, two typical attacks launched by attackers at the communication network layer are Denial of Service (DoS) attacks and deception attacks. [5][6][7] Deception attacks refer to the attacker modifying the control input and measurement data, thus resulting in incomplete or unreliable data resources. Generally, deception attacks can be classified into three types: data replay, data modification, and false data injection.…”

Bipartite synchronization of multi‐agent systems under deception attacks via pinning delayed‐impulsive control

Dai

Guo

et al. 2023

This article aims to investigate the bipartite synchronization problem of multi-agent systems (MASs) under deception attacks. A pinning delayed-impulsive control scheme is proposed to solve the synchronization of MASs under deception attacks that modify the transmitted data information and destroy the data integrity. The time delay can have a gain effect on the stability of the system by using time delay utilization technology. By selecting the appropriate time delay parameters, the convergence speed of the system is effectively improved. Furthermore, cooperative and competitive interactions between agents are considered. Sufficient conditions of the bipartite mean-square bounded synchronization of MASs under deception attacks are theoretically obtained. Finally, the designed numerical simulations illustrate the correctness and effectiveness of our results.
