However, improper selection of <em>kernel sizes</em> may either degrade the estimation performance or slow down the convergence rate. This paper extends and encompasses the baseline MCKF through the development of a projection-based adaptive MCKF (PAMCKF) for continuous-time linear systems with a class of non-Gaussian noises: measurement outliers that are mainly due to sensor failures, cyber-attacks, etc We suggest an adaptation mechanism that exploits the innovation signals to update “on-line” the <em>kernel sizes</em>. The proposed adaptive method is then unified with a modified version of MCKF to achieve robust estimation with low computational effort against measurement outliers without the need for knowing their bounds <em>a priori</em>. The main contribution of this paper is that state and <em>kernel size</em> estimation errors are uniformly ultimately bounded which is formally proven using a deterministic Lyapunov stability argument. Simulations and comparisons to KF and MCKF are carried out to validate the theoretical results and demonstrate the benefits of the proposed filter.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"204 ","pages":"Article 106198"},"PeriodicalIF":2.1,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144653567","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 proposed approach first introduces a sliding mode control scheme with an adaptive control parameter to ensure the satisfaction of coupled equality constraints within a fixed time, regardless of the initial state. Based on this scheme, an innovative node-based distributed optimization algorithm is developed, incorporating a nonlinear adaptive consensus scheme to achieve the optimal solution within a fixed time. The theoretical upper bound for the convergence time is determined by the first positive zero point of a sine function. Furthermore, the algorithm is extended to an edge-based distributed optimization scheme to reduce communication burden, albeit with increased memory consumption. Lyapunov technique is employed to confirm the stability of both the node-based and edge-based methods. To address the singularity issues encountered in the adaptive fixed-time algorithms, the saturation function and the power-ball method are introduced. Finally, the effectiveness and superior convergence performance of the proposed methods are demonstrated through three simulation cases, particularly highlighting their advantages in scenarios with sparse communication networks.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"204 ","pages":"Article 106189"},"PeriodicalIF":2.1,"publicationDate":"2025-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144631559","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 transformation is computed degree-by-degree, similar to previous Taylor-series approaches in the literature.

We derive the explicit algebraic structure for the equations, present rigorous analyses for the solvability and algorithmic complexity of those equations, and provide general purpose open-source software implementations for the proposed algorithms to stimulate broader use of nonlinear balanced truncation model reduction.

The study incorporates limited observation capabilities for both agents, deriving conditions under which the defender can intercept the intruder or the intruder can breach the target. This work formulates the problem as a Game of Kind, introducing a time advantage function that quantifies the game outcome: when the function is non-negative, the intruder dominates the game, selecting an invasion point on the target boundary that maximizes the time advantage (maximizing terminal separation from the defender) to ensure successful penetration; when the function is negative, the defender strategically deviates from the target boundary and utilizes the boundary of dominance region (defined by intersections of the agent isochrones) to derive optimal interception trajectories.

These mappings involve infinite-dimensional nonlinear operators, typically defined through PDEs with spatial variables. For each new coefficient of the PDE, a corresponding gain function must be determined by solving these complex equations. However, this challenge can be addressed by employing a neural operator to learn and approximate the mapping efficiently. In this context, this paper focuses on stabilizing torsional vibrations caused by bit stick–slip behavior in oilwell drilling systems, which are described by a damped wave equation. To achieve this, the second-order torsional vibration dynamics are transformed into a coupled system of <span><math><mrow><mn>2</mn><mo>×</mo><mn>2</mn></mrow></math></span> first-order PDEs. Building on this formulation, we verify the continuity of the mapping from the plant PDE coefficients to the solutions of the kernel PDEs and show that a DeepONet approximation closely mirrors the exact kernel PDEs. Furthermore, we demonstrate that the DeepONet-approximated gains ensure system stabilization, effectively replacing the exact backstepping gain kernels. The stabilizing capability of the proposed approach is supported by theoretical proofs and validated through simulation results. This study extends the work by Toumiet al.
