There are derived rather general formulas, which allow to render both stability regions and regions for specified gain or phase margin. Knowledge of these regions allows to verify a robustness of different controller tuning methods for plants with uncertainties. For the most common plants with time delay of the first and the second order with time delay user-friendly formulas are given. The use of a described approach is shown in the example.","PeriodicalId":6534,"journal":{"name":"2018 Cybernetics & Informatics (K&I)","volume":"1 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88998455","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}

The cooperation among Operational Technology (OT), Information Technology (IT) and people allows to create one smart system to monitor, track, and store patients' healthcare information for ongoing care. Therefore, we provide our case study in which we took hospital data and used cloud services for data storing and machine learning.

Localization and optimization of the trajectory were performed in indoor spaces using the infrared camera StarGazer. The used Mecanum omnidirectional chassis allows great maneuverability, but the movement itself causes deflection from the desired trajectory. The minimization of these deflections was solved by generally standard procedures and then we compared them with the outputs obtained with DKF. The results were quantified and evaluated at the end of the article.","PeriodicalId":6534,"journal":{"name":"2018 Cybernetics & Informatics (K&I)","volume":"15 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80429601","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}
