Here, the WTOD protocol is adopted to allocate resources reasonably in a bandwidth-limited communication network. Under this protocol, each sensor measurement is assigned a predefined priority weight. At each sampling instant, only the measurement with the highest weight can be transmitted while the others are discarded. The aim of this work is to design an <span><math><msub><mrow><mi>H</mi></mrow><mrow><mi>∞</mi></mrow></msub></math></span> filter to ensure the asymptotical stability and finite frequency (FF) <span><math><msub><mrow><mi>H</mi></mrow><mrow><mi>∞</mi></mrow></msub></math></span> interference attenuation level for filtering error systems under the addressed communication protocol.

To address this limitation, this paper proposes a novel Gaussian filter framework for nonlinear stochastic systems. Within the Bayesian estimation framework, an augmented state is designed to handle the delayed measurement. Furthermore, the conditional Gaussian distribution Lemma is applied to correct the predicted state under correlated noise. The proposed framework, which is a generalization of the standard Gaussian filter, proceeds through three steps: state prediction, state update, and measurement noise update. Thus, suitable numerical methods can be used to solve the high dimensional integrals in the proposed framework. Finally, a commonly used nonlinear growth model in stochastic system is used to verify the effectiveness of the proposed Gaussian filter, in which the extended Kalman filter (EKF) and the cubature Kalman filter (CKF) are used to deal with the high dimensional integrals.</div></div>","PeriodicalId":49450,"journal":{"name":"Systems & Control Letters","volume":"208 ","pages":"Article 106310"},"PeriodicalIF":2.5,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145694363","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}

This paper extends the research to higher-order multi-agent systems over periodic switching graphs, allowing the interactions among agents to change periodically. The trajectories of leaders can take the form of trigonometric functions, polynomial functions, or their finite combinations, thereby including step and ramp functions as special cases. The followers are modeled as higher-order integrators, hence including single and double integrators as special cases. To determine the desired positions for the followers, we develop a bearing-based localization technique specifically for periodic switching graphs. Then, we propose a switched bearing-based distributed control law to stabilize the closed-loop system and drive the formation toward the target formation. Moreover, to avoid collisions during the formation evolution, we derive a sufficient condition based on the initial formation.
