However, for discrete-time linear systems (DLS), the looped-function approach is still lacking. A discrete looped-functional approach is proposed to investigate the asymptotic stability of DLS with Markov parameters and aperiodic sampling. Firstly, the discrete-time sampled-data system is represented as a time-delay system by using the input delay approach. Furthermore, a relaxed equivalent asymptotic stability condition is proposed, which only requires that the system state tends to zero at ordered and non-adjacent discrete instants <span><math><mrow><mo>{</mo><msub><mrow><mi>t</mi></mrow><mrow><mi>k</mi></mrow></msub><mo>}</mo></mrow></math></span>, which effectively simplify the complexity of the stability analysis. Moreover, for discrete-time systems under aperiodic sampling, based on the above equivalent condition, a novel discrete looped-functional is constructed. As an extension of the continuous looped-functional, the discrete looped-functional has the characteristic that its value is zero at <span><math><mrow><mo>{</mo><msub><mrow><mi>t</mi></mrow><mrow><mi>k</mi></mrow></msub><mo>}</mo></mrow></math></span> and it does not impose strict constraint on the positive definiteness of the functional.

The validity of these results is verified by using a classical example, demonstrating a larger upper bound for the sampling interval compared to existing results.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"202 ","pages":"Article 106121"},"PeriodicalIF":2.1,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143913215","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}

Different from most research perspectives, the FDI attack is modeled with high randomness in value, target, and period. The CPSs architecture with a group of sensors and estimators is considered in the distributed estimation. A reconstructed measurement, depending on the combination of an attack detector and estimation results, is established to obtain accurate measurement data when the transmitted measurements are falsified by FDI attacks. The two-layer estimator, which includes measurement fusion estimation and interactive consensus estimation, is advanced to achieve secure consensus-based distributed estimation. In contrast to current approaches, due to accumulating measurement data from different sensors, and adopting the appropriate consensus gain matrix obtained by the Lyapunov function of estimation error, the proposed approach can realize consensus distributed estimation while requiring fewer communication resources. In addition, numerical simulations of the 2-dimension tracking system are provided to illustrate the effectiveness of the proposed method.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"202 ","pages":"Article 106115"},"PeriodicalIF":2.1,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143886058","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}

To address this, we apply deep reinforcement learning to suggest feedback laws for a discretized system that only rely on these accessible, real-world measurements, obtainable through methods like pheromone traps.
