A continuous control scheme is provided to enable HMASs to solve fixed-time containment control problems with unknown DoS attacks and arbitrary initial conditions. To reduce the frequency of controller updates, a novel control strategy based on event-triggered conditions has been designed, which can settle the fixed-time containment control issue without requiring continuous controller updates. In the scenario where the initial states of the systems are bound, an improved event-triggered control scheme with periodic event-triggered conditions is designed, which can avoid continuous controller updates and does not need continuous system messages. Compared with many existing results, all the designed control schemes can settle fixed-time containment issues even when the DoS attacks and initial conditions are unknown. Moreover, the given event-based control schemes can avoid Zeno-behavior.

This paper studies the distributed constrained optimization problem over the weight-unbalanced directed network, considering local inequality and coupled equality constraints. First, a distributed consensus scheme with a time-based generator is provided to estimate the left eigenvector of the Laplacian matrix. Building on this estimator, an adaptive proportional–integral-based gradient flow scheme is designed to solve the coupled constraint, introducing a time-varying control parameter to remove the requirement of the Laplacian matrix’s eigenvalues. Subsequently, a fully distributed primal–dual optimization method is proposed based on KKT conditions for the constrained optimization problem with a nonsmooth objective function. The optimality and convergence analysis are conducted through Lyapunov theory under the strongly connected and weight-unbalanced directed network. Finally, the established method is applied to the economic dispatch problem in smart grids.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"204 ","pages":"Article 106211"},"PeriodicalIF":2.5,"publicationDate":"2025-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144858208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the cyber layer, HZMRS models attack infiltration dynamics by incorporating tactics and techniques from the ICS MITRE ATT&CK framework, thereby systematically enhancing the modeling of adversarial progression. For the power network as the physical layer, HZMRS employs the Transient Energy Function (TEF) approach, instead of linear approximations and small-signal stability criteria, to effectively capture the severe transient disturbances triggered by DoS attacks. To solve the HZMRS game, we propose a Robust Accelerated Value Iteration (RAVI) algorithm that ensures robust performance against worst-case transition probabilities and employs prioritized sweeping to accelerate convergence. We also provide a proof of convergence for this algorithm. Unlike classic algorithms, RAVI is designed to handle model uncertainties arising from zero-day vulnerabilities and incomplete information about attacker capabilities. Based on the outcome of the HZMRS, we introduce a novel metric called <em>Cyber Security Index Level</em> (<span><math><mrow><mi>C</mi><mi>I</mi><mi>L</mi></mrow></math></span>), which quantifies the probability of successful physical layer intrusion after breaching the cyber layer. The proposed model is validated through simulations conducted on the IEEE 9-bus power network, considering an attack scenario adapted from the BlackEnergy v3 malware. Comparative results show that RAVI achieves successful convergence under uncertainty, and the derived security metrics offer improved reliability and practical relevance for real-world CPS applications.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"204 ","pages":"Article 106207"},"PeriodicalIF":2.1,"publicationDate":"2025-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144711583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
