If they are precise in terms of transients, they are difficult to implement in real time. In case of insensitivity in the transient modes, they are inaccurate in a large range for the purposes of automation and technical operation. Adequacy analysis and subsequent adaptation is a possible approach with good results in the presence of an appropriate workable model.","PeriodicalId":441906,"journal":{"name":"2022 8th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130099672","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}

There is a significant change in the forces of dry friction at rest which is the reason for the friction power reduction and the mechanical losses of the pistons with a special form of the contact surface.","PeriodicalId":441906,"journal":{"name":"2022 8th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126875275","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}

With each passing day we have to produce more than less. A key element of this cycle is the optimization of production. Increasingly, it is necessary to look for applied alternative methods and optimal solutions. Remote sensing is a very good alternative in modern technology. In our country, especially in intensive crops, such studies are almost non-existent. In connection with this and the new trends for the development of the European Union, part of which is the introduction of artificial intelligence in agriculture, it is necessary to look for new alternatives in the cultivation of crops.
