For the first time, we present a quantitative analysis of the unbiased ES. We consider delays with a large known constant part and a small time-varying uncertainty. Such delays may arise when measurements together with a time stamp are transmitted to ES controller via communication network. For the quantitative bounds, we assume that the Hessian is uncertain from a known range. By applying a delay-free transformation, explicit quantitative conditions in terms of simple scalar inequalities depending on the tuning parameters are established which ensure the exponential unbiased convergence of the ES system. Moreover, the corresponding results for the classical ES are presented. For globally quadratic maps, our results are semi-global, whereas for locally quadratic static maps, we provide a bound for the region of convergence. Appropriate ES parameters can be found for any large known delay and small enough delay uncertainty. Two numerical examples from the literature illustrate the efficiency of the proposed method.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"205 ","pages":"Article 106256"},"PeriodicalIF":2.5,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145220780","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}

Modelling the pressure and flow transients in the network via linearized transmission line PDEs (partial differential equations), it is shown how the network may be represented by an interconnection (cascade) of systems of linear hyperbolic PDEs, with a depth determined by the network topological radius and width the number of network inlets and outlets. Information about leaks in the network is summarized in a structured way in an unknown additive vector parameter entering the distal boundary of the last PDE system. It is shown how the leak parameter may be used to compute the total amount leaking from the network regardless of how leaks are distributed in the network, and in the event of point leaks entering the network sequentially, pinpoint the location of the leaks in the network. Two methods are provided to estimate the leak parameter: (1) An algebraic calculation for when the system is in steady-state and (2) an adaptive boundary observer for the interconnected system of PDEs with asymptotic convergence guarantees for transient dynamics. A simulation example is provided to demonstrate the leak detection method with transient data.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"205 ","pages":"Article 106255"},"PeriodicalIF":2.5,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145220779","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}

The adaptive boundary observer is designed to estimate the system state and the unknown parameters. In order to facilitate the design of the observer, the observer error system is transformed into a target system by a Volterra integral transformation and a state transformation, and then a swapping filter design method is proposed by combining the method of least-squares with a variable forgetting factor. The stability analysis shows the exponential convergence of both the state estimation error and the parameter estimation error under the persistent excitation condition of the filter. Finally, the obtained theoretical results are applied to the linearized Aw–Rascle–Zhang (ARZ) traffic flow model involving the in-domain relaxation time and the boundary flux fluctuation uncertainties, which verifies the effectiveness of the proposed method.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"205 ","pages":"Article 106243"},"PeriodicalIF":2.5,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145106527","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}
