Existing research often simplifies agent shapes to particles or circles, neglecting the real shapes like unmanned ships and vehicles, which can result in inefficient use of spatial resources. To solve this problem, a new method for calculating the relative distance between convex polygonal agents is introduced. A potential function incorporating attractive and repulsive forces is designed based on this relative distance. The attractive function promotes cohesion, while the repulsive function prevents collisions. A finite cut-off function is used to design the repulsive function to avoid infinite repulsion when agents are too close. A flocking reference trajectory is set for movement, and an obstacle-avoidance reference trajectory is assigned for avoiding obstacles when the distance between the agent and the obstacle is less than the safe distance. The proposed control law integrates potential function and reference trajectory to achieve both flocking and obstacle avoidance. The effectiveness of the proposed control algorithm is validated through simulation on agents of different shapes in both obstacle-free and obstacle environments.</div></div>","PeriodicalId":17283,"journal":{"name":"Journal of The Franklin Institute-engineering and Applied Mathematics","volume":"362 15","pages":"Article 108026"},"PeriodicalIF":4.2,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144989224","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}

Specifically, for the connectivity-maintained attacks, a time-varying and a time-invariant consensus control schemes based on the designed event-triggered mechanism are presented for the known and unknown attacks, respectively. Furthermore, to achieve consensus even though the connectivity of communication network is broken, a dynamic periodic event-triggered controller based on periodic sampling observer is presented for the connectivity-broken attacks. It can be proved that all the proposed control schemes can solve the consensus issues under different types of DoS attacks.

The sensor resolution is regarded as a key indicator of measurement accuracy and effectively handled by the upper boundary technique to deal with the uncertainty caused by sensor resolution in this paper. The measurement output is transmitted to the remote filter through a time-correlated fading channel, where the channel coefficient is described by a certain dynamical process. The purpose of this paper is to design a resilient distributed filter to ensure that the filter error covariance has an upper bound in the presence of some fluctuations of the gain parameters. With the help of trace operations, the gain parameters of the desired distributed filter are obtained in terms of the solutions to a set of recursive equations. In addition, the exponential boundedness in the mean square of the filtering error system is analyzed.

The motivation of this study is to explore whether an adaptive tracking control strategy can be formulated under conditions of unknown nonlinearity and non-affine faults, ensuring all signals remain bounded within a fixed time while maintaining the stability of the closed-loop system. Unlike traditional methods, this paper employs dynamic surface technology and event-triggered rules for controllers and actuators, effectively addressing the complexity explosion problem in existing works. A specific compact set is constructed, and using the fuzzy logic approximation method, it can be proven that the fuzzy approximation is effective, all closed-loop signals are bounded, and asymptotic tracking is achieved. The adverse effects due to unclear time delays are mitigated by selecting appropriate compensation functions.
