Also, controlling vibrations while maintaining stability at high speeds requires advanced controllers and engineering solutions. However, the most traditional controllers include dampers and linear controllers. A few studies have considered HST’s nonlinear dynamics and stability concerns. This paper introduces a new effective idea based on the Active Rotary Inertia Driver (ARID) system. The controlled ARID system ensures stability by actively manipulating rotational inertia through a mass disk. The designed controller is applied for a case-study plant, and the whole closed-loop dynamics are considered to be unknown. Considering the nonlinear complexity of HST motion, adaptive type-3 fuzzy logic systems (T3-FLSs) are developed for modeling. The proposed controller autonomously identifies closed-loop dynamics, independent of predefined ARID equations and HST’s models. Both control gain and nonlinearities are estimated using adaptive T3-FLSs. The T3-FLSs are updated online using Lyapunov adaptation rules. A compensatory parallel controller is also designed to counteract disturbances and T3-FLS estimation errors. The efficacy of the designed approach is validated through comprehensive experiments and simulations under various operational conditions. The overall performance is analyzed in terms of cost, time, frequency domain metrics, and energy efficiency.</div></div>","PeriodicalId":17283,"journal":{"name":"Journal of The Franklin Institute-engineering and Applied Mathematics","volume":"362 16","pages":"Article 108115"},"PeriodicalIF":4.2,"publicationDate":"2025-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145222534","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}

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.
