Hospital beds are designed to ensure static safe configuration of patients mostly in supine position with some motion capability in elevating trunk or legs. More capability is today requested for permitting bedded patients to avoid inconveniences up to further accidents and to facilitate therapy treatments and clinical conditions. A robotized design solution for hospital beds with movable segments is proposed for patients of COVID-19 in intensive and sub-intensive care treatments with the aim to help therapies and motion treatments for better physical conditions. The proposed design is analyzed in terms of mechanism structure and motion operation towards medical effects that can be appreciated as supporting/mitigating critical conditions in hospital applications.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121081490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We determine amplitude limits for the step reference that guarantees the regional closed-loop stability and constraints fulfillment, using invariance and contractivity properties of polyhedral sets, such that the Internal Model Principle remains valid in the polyhedral region. The first main result is based on the positive-invariance property applied to an extended state-space representation that takes the reference model into account, leading to more complex conditions than the ones based on the $Delta$-invariance property. Based on these two complementary results, a set of bilinear programming problems is proposed to find solutions for the associated constrained tracking problem. A numerical example illustrates the proposal.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122506462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Felisa Córdova","doi":"10.1109/ICAACCA51523.2021.9465304","DOIUrl":"https://doi.org/10.1109/ICAACCA51523.2021.9465304","url":null,"abstract":"This lecture aims to provide an international forum to discuss the main ideas about cyber-social-technologicalcognitive approach present in indifferent ecosystems. Nowadays, investments that promote disruptive technologies and digital transformation accompanied by advances in Industry 4.0 enable the development of intelligent and smart systems in different domains. The hyperspace allows the interconnection of multiple spaces of computers and networks which are interlinked with each other in cyber, social, technological and cognitive domains. The CTSC approach is present today in indifferent ecosystems. In this context, conceptual models and architectures that integrate relevant attributes present in hyperspace are discussed focusing in Smart Ports, Green Energy Systems, and Health and Wellness Systems. In the case of Smart Ports, the Fifth generation ports are automated and sensorized, intensive in the use of artificial intelligence tools, sensors, RFID radio frequency, differential GPS system, Internet of Things (IoT), data management for Big Data, among others. Moreover, Green energy system's cyber domain enables technologies and processes to operate seamlessly such as grid flexibility enabled by IoT, and digital networks; smart metering; and the new concept of energy consumer producer “prosumer”. In the field of Health and Wellness Systems the pandemic has given a great opportunity to CSTC in the application of new methods, models, practices, and technologies such as Robotics, Virtual and Augmented Reality, Big Data, Artificial Intelligence, and Analytics. All of them have extraordinary potential in the field of medicine as it allows to analyze large volumes of data in order to predict, prevent or customize treatments in different pathologies. Today different open source data platforms and AI are used to track the spread of the disease. The role of the Internet of services (IoS) stands out as an ecosystem that takes over complex collaborative applications using interoperable resources across platforms and cloud storage. It also addresses advances in AI, neuroscience, and cognitive sciences that enable the development of Human Body Communication (HBC) and Human Information Processing (HIP) and open the door to multiple applications in the Internet of the People (IoP) domain.","PeriodicalId":328922,"journal":{"name":"2021 IEEE International Conference on Automation/XXIV Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115545531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
