The integration of GANs and DDPMs facilitates the generation of realistic synthetic data and also improves the model’s ability to detect subtle and complex anomalies in industrial environments. To further strengthen data privacy, differential privacy techniques are incorporated to ensure the confidentiality of sensitive data.

By introducing a distributed estimator, each follower can track the leaders’ center despite partial communication losses, while a carefully designed controller guarantees rapid convergence to the surrounding formation.

Existing studies have often failed to achieve a uniform distribution of robots across multiple targets and, in most cases, only succeeded in tracking rather than capturing the targets. To address these limitations, this paper proposes a round-up control algorithm that consists of two stages: (1) Tracking and enclosing: Each target is assigned a dynamic influence area that adjusts according to the number of surrounding robots, enabling robots to redistribute themselves and tracking all targets with a balanced number. (2) Intercepting and capturing: Once the number of robots within a target’s influence area reaches a predefined threshold, the robots gradually converge their velocities. Together with a repulsive potential function designed between robots and targets, this mechanism effectively restricts target movement and enables capture. Furthermore, a new potential function with increased well depth is introduced to accelerate inter-robot interactions and reduce the time required to complete the rounding-up process, while maintaining effective obstacle avoidance. The stability of the proposed control strategy is rigorously analyzed using Lyapunov’s theorem and LaSalle’s invariance principle. Simulation results validate the effectiveness of the algorithm, demonstrating uniform target allocation, successful capture, and significant improvements in efficiency compared with existing methods.</div></div>","PeriodicalId":17283,"journal":{"name":"Journal of The Franklin Institute-engineering and Applied Mathematics","volume":"362 16","pages":"Article 108111"},"PeriodicalIF":4.2,"publicationDate":"2025-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145222531","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}
