Also, finite-time control is a vital methodology that allows counteracting the effect of disturbances, providing robustness to the closed-loop system. Based on these two essential topics, this manuscript proposes a new observer-based finite-time scheme that allows controlling second-order systems affected by matched disturbances. The proposed methodology enables the perturbed system to follow a given reference signal in a finite time. In the new proposal, the control signal is split into three parts. In the first part, an observer estimates and compensates for various endogenous or exogenous disturbances. Then, the system error dynamics are transformed into a decoupled system with bounded disturbances through the second control part. Finally, a finite-time controller is designed to accomplish finite-time convergence of the error signal. A formal mathematical development utilizing the Lyapunov theory demonstrates the effectiveness of the new control scheme. Also, the novel controller is compared against two existing observer-based finite-time controllers, and the remarkable performance of the latest proposal and its low power demands are demonstrated via numerical analysis.</div></div>","PeriodicalId":14660,"journal":{"name":"ISA transactions","volume":"161 ","pages":"Pages 97-108"},"PeriodicalIF":6.3,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 strategies often rely on restrictive assumptions or are obtained sequentially, resulting in poor stability and performance. To overcome these limitations, this study introduces a developed static output feedback framework that stabilizes and simultaneously tunes multiple parameters in various dynamic control systems. The proposed methodology combines a systematic analytical procedure with a software-based implementation, enabling proper performance under varying system types, orders, and parameter sets. Indeed, the introduced tuning approach enables the simultaneous adjustment of all control system parameters, accommodating the designer’s preferences regarding the number of parameters to be tuned and the control objectives. Its effectiveness and efficiency are demonstrated through extensive simulations and real-time experiments in aerospace, robotics, and electric systems. Results indicate that this approach covers significant system variations without compromising stability or performance, distinguishing it from the conventional tuning methods. These outcomes offer new insights into the importance of simultaneously retuning control system parameters due to technical and economic issues. It is worth emphasizing that the proposed approach provides a comprehensive plan for designing or tuning controller parameters simultaneously and extends the applicability of static output feedback control theory to a wider range of dynamic control systems.</div></div>","PeriodicalId":14660,"journal":{"name":"ISA transactions","volume":"161 ","pages":"Pages 261-275"},"PeriodicalIF":6.3,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143904569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
