In this contribution, models with up to three parameters are estimated by means of a single asymmetrical relay experiment. Then a stable low order transfer function with a time delay term is identified by a relay experiment. Autotuning principles then combine asymmetrical relay feedback tests with a control synthesis. Two algebraic control syntheses then are presented in this paper. The first one is based on the ring of proper and stable rational functions <em>R<sub>PS</sub></em>. The second one utilizes a special ring <em>R<sub>MS</sub></em>, a set of RQ-meromorphic functions. In both cases, controller parameters are derived through a general solution of a linear Diophantine equation in the appropriate ring. A final controller can be tuned by a scalar real parameter <em>m>0</em>. The presented philosophy covers a generalization of PID controllers and the Smith-like control structure. This contribution deals with the implementation of proposed autotuners and presents some illustrative examples.</p></div>","PeriodicalId":37894,"journal":{"name":"IFAC-PapersOnLine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2405896324004518/pdf?md5=6224c59cfe3b35ce71f041ce4db797e6&pid=1-s2.0-S2405896324004518-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141985721","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition to lane changes that every vehicle may encounter on roads, the eco-driving connected automated vehicles (CAVs) are subject to induced types of lane changes of manually-driven vehicles (MVs), a cut-in of an MV to the front of a CAV from an adjacent lane, and an escape of an MV from behind a CAV to an adjacent lane. So far, very few studies have considered the impact of lane changes while designing the ecodriving strategies and evaluated the eco-driving performance with respect to lane-changing disturbances in credible simulation environments; and almost no existing work has addressed both lateral and longitudinal disturbances for eco-driving. This paper has developed a generic and deployable eco-driving strategy for CAVs under a unified rolling-horizon optimal control framework that can deal with both longitudinal and lateral disturbances of MVs without assuming communications between CAVs and MVs. The performance of this disturbance-rejection eco-driving strategy was thoroughly evaluated with regard to a multilane urban network, using the microscopic traffic simulator SUMO. The strategy was demonstrated very effective and robust, and similar results were little reported before.</p></div>","PeriodicalId":37894,"journal":{"name":"IFAC-PapersOnLine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2405896324004026/pdf?md5=8f9200f73396146faacc05a37f6ee602&pid=1-s2.0-S2405896324004026-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141960959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Machine learning techniques have also been utilised in culturally significant work across Asia and Africa in sectors such as education, healthcare, agriculture, and Cultural Heritage with the goal of improving the life and wellbeing of people in these regions.

However, the inherent issue of noise interference for the highly sensitive sensing element is accompanied, raising the challenge of achieving reliable stability. The proposed method aims to effectively reduce the deviation in the measurement of highly sensitive QTF sensing elements in a digitized measurement system.

While gerontechnology presents an opportunity to mitigate the effects of aging and the application of intelligent solutions in rural settings is on the rise, our examination uncovers a dynamic mix of both prospects and hurdles, highlighting the need for broader, interdisciplinary studies. The prevalent research tends to concentrate on the technological, energetic, and agricultural aspects, often overlooking the importance of social services and care for the elderly. Through a detailed examination, we’ve pinpointed several areas lacking in research, such as the necessity for long-term studies, the involvement of users in the design process, and thorough economic evaluations, as well as the need to address ethical, privacy, and societal concerns. Our analysis indicates that, although technological progress offers the potential to significantly improve the lives of seniors in smart villages, fully achieving these advantages necessitates bridging these identified research voids. Future studies should focus on creating accessible, user-focused technologies and approaches that cater to the varied needs and wishes of the elderly, through joint initiatives spanning healthcare, technology innovation, urban planning, and social studies. Adopting this comprehensive strategy will not only improve the quality of life for the elderly but also acknowledge their significant contribution and value in the context of smart villages, aligning with IFAC’s mission to leverage innovation and technology for enhancing human life quality.</p></div>","PeriodicalId":37894,"journal":{"name":"IFAC-PapersOnLine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2405896324002441/pdf?md5=1129a8b133b78588415807b4c32e945d&pid=1-s2.0-S2405896324002441-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141951577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
