The core of the method is a novel measurement delay-compensated phase-leading extended state observer (MPLESO), which integrates a synchronized input filter to suppress noise while generating an effective phase lead to offset delay-induced dynamics. A lead time-constant formulation is derived to guarantee zero steady-state error, expand disturbance estimation bandwidth, and ensure closed-loop stability. Comprehensive simulations demonstrate that MPLADRC achieves superior disturbance rejection, faster response, and improved tracking accuracy compared with conventional LADRC, delivering consistent performance gains exceeding 35.8%.</p>","PeriodicalId":50382,"journal":{"name":"IET Control Theory and Applications","volume":"20 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/cth2.70116","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147562911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the use of a surrogate signal is imperative. In this research, we present the design and associated stability of a saturation function based velocity estimator/observer for a general class of mechatronic systems. The proposed method estimates velocity without requiring prior knowledge of system dynamics. A novel adaptive update algorithm automatically adjusts the observer gains, eliminating the need for manual gain-tuning. We establish the stability of the velocity observer, along with the auto-tuned gain update rules, through a Liapunov-type analysis. Experimental validation on a rotary inverted pendulum demonstrates the effectiveness of the proposed method. Two case studies are conducted: the first compares the real-time performance of the proposed observer with a signum function based observer, while the second evaluates the observer's reliability with constant gains, highlighting its capability to support control design and maintain robustness against external disturbances.</p>","PeriodicalId":50382,"journal":{"name":"IET Control Theory and Applications","volume":"20 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/cth2.70077","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147562817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As was shown in other works, applying the act-and-wait concept to a PD position control increases the available range of proportional gains, which reduces the steady-state error of dry friction. In this paper, we focus on the vibration phenomena at the boundaries of the dynamic stability from the aspect of the vibration spectrum. We consider a single-degree-of-freedom mechanical model of DC actuators that contains significant effective damping. At different types of stability limits, new analytical and semi-analytical results are derived for the vibration spectrum.

These MRAS estimators estimate stator resistance and PM flux by analysing the error between the stator currents measured as the reference model and the stator currents generated by the adaptive model. The performance of the proposed estimators is assessed through simulation studies. Furthermore, the proposed approach is compared to a conventional MRAS employing a fixed-gain proportional-integral (PI) controller.

To ensure both transient and steady-state performance of attitude tracking, prescribed performance functions are introduced, and coordinate transformations are employed to convert constrained tracking errors into unconstrained states. Based on the transformed errors and the command-filtered backstepping recursive design procedure, a predefined-time fault-tolerant controller incorporating radial basis function neural networks (RBFNNs) is systematically developed. RBFNNs are utilized for online estimation and compensation of the system's unknown dynamics, thereby improving control accuracy. The proposed controller guarantees that spacecraft attitude errors converge to minimal neighbourhoods of the origin within a predefined settling time. Finally, comparative simulation results validate the effectiveness of the proposed control approach.</p>","PeriodicalId":50382,"journal":{"name":"IET Control Theory and Applications","volume":"20 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2026-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ietresearch.onlinelibrary.wiley.com/doi/epdf/10.1049/cth2.70114","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147568434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
