This paper examines uniform exponential stability for a semi-discrete scheme applied to a one-dimensional Euler–Bernoulli beam with bending moment feedback, which is sharp contrast to scenarios involving shear force feedback control. For decades, establishing the exponential stability of this continuous PDE has posed a significant challenge, primarily due to the absence of an appropriate time domain multiplier. This obstacle, in a way, spurred the advancement of the frequency domain multiplier method in the 1980s. Notably, the frequency multiplier utilized here is a specified exponential function of both concerned varying real numbers and spacial variable, distinguishing it from recent studies on the Schrödinger equation. Consequently, the question of uniform stability for the semi-discrete scheme has remained unresolved for an extended period. In this paper, we first establish the exponential stability of the continuous system using the frequency domain method. Subsequently, we employ an order-reduction technique to devise a spatially semi-discretized finite difference scheme for this continuous system. Ultimately, to demonstrate the uniformly exponential stability of the resulting semi-discretized system, we adopt the discrete frequency domain method, with the proof mirroring the approach used for the continuous system. The approach presented in this paper, which effectively addresses the specified exponential function involving both concerned varying real numbers and spatial variables, holds potential for application to other PDEs that encounter analogous challenges.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"203 ","pages":"Article 106136"},"PeriodicalIF":2.1,"publicationDate":"2025-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144241135","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 primary goal is to search the Nash equilibrium of a non-cooperative game where each player minimizes its private object with others’ strategies unchanged. Meanwhile, a specific social cost is taken into account during decision-making and is optimized within the equilibria of the underlying game. Such an optimal Nash equilibrium problem can be modeled as a distributed optimization problem with variational inequality constraints. We consider the scenario where the objective functions of both the underlying game and social cost optimization problem have a special aggregation structure. When each player has access only to its local objectives and cannot directly know the decisions of all players, a distributed algorithm is highly recommended. By utilizing the Tikhonov regularization and dynamical average tracking technique, we propose a distributed coordination algorithm by introducing an incentive term to the gradient-based Nash equilibrium seeking, so as to intervene in players’ decisions to improve the system efficiency. We prove its convergence to the optimal Nash equilibrium of a monotone aggregative game, and carry out numerical experiments to empirically demonstrate the algorithm performance.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"203 ","pages":"Article 106142"},"PeriodicalIF":2.1,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144222138","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}

For linear dynamical systems the energy functions are known to be quadratic polynomials and various low-rank approximation techniques allow for computing them in a large-scale setting. For nonlinear problems computing the energy functions is significantly more challenging. In this paper, we investigate a special class of nonlinear systems that have a linear state and a polynomial output equation. We show that the energy functions of these systems are again polynomials and investigate under which conditions they can effectively be approximated using low-rank tensors. Further, we introduce a new perspective on the well-established balanced truncation method for linear systems which then readily generalizes to the nonlinear systems under consideration. This new perspective yields a novel energy-based model order reduction procedure that accurately captures the input–output behavior of linear systems with polynomial outputs via a low-dimensional reduced order model.

The discrete-time dynamics consist of deterministic motion and random jumps. The deterministic motion is given by the direction of a drift vector field. The random jumps are triggered by a finite number of independent count processes and the corresponding state transitions are given by jump vector fields. One may think of the discrete-time system as an input-affine with drift, where the count processes act as inputs in the directions of the jump vector fields. In each time step, we allow an activation of multiple jump vector fields, which is different from the corresponding continuous-time model in which, almost surely, only one jump occurs at each time instant. The proposed discrete-time model also includes a user-prescribed step size, which allows approximations of continuous-time processes. In the limit of vanishing step size, the sample paths of the discrete-time model converge almost surely to the sample paths of a continuous-time piecewise deterministic Markov process. We also characterize mean-square exponential stability of the model under the assumption of linear drift and jump vector fields.
