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":"2025-11-01","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}

It investigates the impact of fading networks on achieving output feedback consensus in multi-agent systems (MASs). First, for identical fading networks, we establish the mean-square stability (MSS) of a dual result through state transformation and provide conditions for MASs to achieve mean-square consensus in both undirected information flow (UIF) and balanced directed information flow (BDIF) topologies, utilizing the Schur complement lemma and Lyapunov methods. These conditions are closely related to the fading statistics and the information flow topology (IFT). Next, for non-identical fading networks, under state feedback, we employ the edge Laplacian operator and construct agent dynamic models on the edges, providing analytical sufficient conditions for the system’s MSS. These conditions can be numerically verified via linear matrix inequality (LMI) feasibility. Moreover, separate design algorithms for output feedback and state feedback controllers are provided, derived from feasible solutions to modified Riccati inequalities (MRIs). These algorithms can directly utilize IFT and channel fading statistics for parameter calculation, making them easy to implement. Finally, the theory is applied to a real-world vehicle platoon coordinated control problem, and simulation results comparing theoretical and practical models are presented to validate its effectiveness and applicability. Results indicate that even in the presence of fading, the designed control strategies can ensure the vehicle platoon maintains its desired speed and longitudinal spacing.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"205 ","pages":"Article 106257"},"PeriodicalIF":2.5,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145267880","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 sensor network among the multi-robot system is described by a general directed graph, which contains a directed spanning tree with the root node denoting the leader. A dynamic control law consisting of an observer and a velocity controller, is designed based on the feedback of measurements on the relative positions and orientations. Particularly, the proposed control law can be implemented without using any communication provided that the reference velocities are prior set, which makes it feasible in a decentralized manner. The small-gain theorem is employed to deal with stability analysis on the augmented closed-loop system. A low-gain parameter in the observer ensures that the small-gain condition can be satisfied. The global asymptotic stability of the augmented multi-robot closed-loop system is guaranteed by the proposed small-gain approach. More interestingly, the proposed dynamic control law is robust to measurement errors in relative positions and orientations.

We are primarily interested in an intricate system, i.e., the second-order unstable plant with a zero relative degree that is accompanied by at least one unstable pole and non-minimum phase dynamics, both implemented by the proportional and proportional–integral (PI) type regulators. More specifically, we shall examine three scenarios of the system ranging from the worst case of two unstable poles and two minimum phase zeros to the case of one unstable pole and one minimum phase zero. For each class of systems, we furnish the bi-dimensional feasible horizons for the controller parameters of PI regulators. Drawing upon the feasible domains, we derive the explicit expressions of the optimal robustness margin against unknown uncertainties. Beyond that, we determine the regulator parameters for accomplishing the maximum margins, i.e., the optimum proportional and integral gains. At last, we extend to explore the optimum robustness margin achievable with a PI regulator for third-order non-minimum phase systems. Our results illustrate that the optimal robustness margins obtainable are dependent on the locations of the system’s unstable poles and non-minimum phase dynamics while attaining the optimized margin is relevant to the control parameters of the PI regulator, thus casting insight upon the design and adaptation of the regulator parameters.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"205 ","pages":"Article 106225"},"PeriodicalIF":2.5,"publicationDate":"2025-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144989546","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}
