Despite this beneficial linearization, one significant hindrance is that the system constraints have a convoluted form in the new space (the flat output space), which is usually disregarded in the literature or bypassed via conservative approximation of the feasible domain. In this paper, based on a pre-stabilization design and a novel input saturation component, the nonlinear input constraints are particularly handled for the position tracking problem of quadcopters in the flat output space. While the system’s stability is shown to hold by Lyapunov arguments, the practical viability of the method is validated both in simulation and experiments over a nano-drone platform. Moreover, with the explicit solution introduced for the proposed saturation function, this flatness-based saturated controller not only ensures stability and constraints satisfaction, but also requires low computational effort, allowing possible embedded implementations.</div></div>","PeriodicalId":50489,"journal":{"name":"European Journal of Control","volume":"84 ","pages":"Article 101236"},"PeriodicalIF":2.5,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144106721","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}

Typically, these algorithms consider a model structure that lacks parsimony and offers limited physical interpretability. The objective of this paper is to develop a real-time parameter estimation algorithm aimed at identifying time-varying dynamics within an interpretable model structure. An additive model structure is adopted for this purpose, which offers enhanced parsimony and is shown to be particularly suitable for mechanical systems. The proposed approach integrates the recursive simplified refined instrumental variable method with block-coordinate descent to minimize an exponentially-weighted output error cost function. This novel recursive identification method delivers parametric continuous-time additive models and is applicable in both open-loop and closed-loop controlled systems. Its efficacy is shown using numerical simulations and is further validated using experimental data to detect the time-varying resonance dynamics of a flexible beam system. These results demonstrate the effectiveness of the proposed approach for online and interpretable estimation for advanced monitoring and control applications.</div></div>","PeriodicalId":50489,"journal":{"name":"European Journal of Control","volume":"84 ","pages":"Article 101238"},"PeriodicalIF":2.5,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144106720","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}

First, by introducing a new type of prescribed-time functions defined on the whole time domain, we develop a novel prescribed-time stability theory. Then, a new type of disturbance observers is constructed to exactly estimate the external disturbance within a prescribed time. Based on these preparations, an adaptive prescribed-time fault-tolerant tracking control approach is developed. The combination of the proposed prescribed-time disturbance observer and the adaptive technology is employed to compensate the influence of unknown disturbances and actuator faults. To further reduce the computation complexity, a command filter is used to approximate the virtual control function and then a prescribed-time stable system is designed to compensate the approximation error. Compared with existing results, the designed prescribed-time controller does not involve infinite variables, moreover the tracking objective is completed at the prescribed time and maintained after the prescribed time. Finally, the effectiveness of the proposed controller is validated through simulation results.</div></div>","PeriodicalId":50489,"journal":{"name":"European Journal of Control","volume":"84 ","pages":"Article 101234"},"PeriodicalIF":2.5,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143895693","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}
