To study the robust stability of the automatic irrigation flow control system in the stabilization column, a typical scheme of the regulation system is considered. To describe the problem, a general view of the denominator polynomial of the transfer function of an automatic irrigation flow control system in a stabilization column is obtained. For the robust stability of the automatic irrigation flow control system in the stabilization column under the influence of disturbances, the task of estimating the probability of stability of the family of polynomials of the denominator of the transfer function of the automatic control system is set. A family of polynomials of the denominator of the transfer function of an automatic irrigation flow control system in a stabilization column with uncertainty parameters varying in a cube is considered. The problem of estimating the probability of stability of a family of polynomials of the denominator of the transfer function of an automatic irrigation flow control system in a stabilization column is reduced to solving problems: sample generation and probability estimation by frequency. To assess the probability of stability of the family of polynomials of the denominator of the transfer function of the automatic irrigation flow control system in the stabilization column, four polynomials, including the nominal one, are given. Based on generating a sample of one hundred independent random variables, calculating the corresponding polynomials and checking their stability, the considered family of polynomials of the denominator of the transfer function of the automatic irrigation flow control system in the stabilization column has stability with a probability close to unity.","PeriodicalId":273068,"journal":{"name":"Proceedings of Tomsk State University of Control Systems and Radioelectronics","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126770158","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}

Over the past 10 years, UAV measurement technology has changed significantly and has become popular due to its versatility and ease of use in commercial and scientific research. It should be noted that the methods of processing one-time received images allow solving various scientific and practical problems, however, during monitoring, when the dynamics of the state of objects (surface types) of the same territory is studied, the methodology and software remain questionable. One of the problems that hinder the study, for example, the dynamics of the state of objects on an agricultural field, is the radiometric accuracy of the obtained UAV images. In practice, the radiometric accuracy of measurements allows considering various lighting conditions at different periods of the day and year, by relevant types of digital sensors (digital cameras) used. The study is aimed at enabling a better flexibility when studying the dynamics of the state of objects located on the same territory at different times by taking into account the radiometric errors of UAV images when mapping the state of vegetation. The research methodology uses the real images of the UAV obtained from June to August 2019 for an agricultural field with winter wheat.","PeriodicalId":273068,"journal":{"name":"Proceedings of Tomsk State University of Control Systems and Radioelectronics","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126830368","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 purpose of the control is to find the precise positioning of the transported cargo with the damping of its pendulum oscillations and the parrying of external disturbances. The dynamics of an overhead crane when moving a trolley along one axis is described. The proposed control method is based on an adaptive control scheme with an identifier and an implicit reference model using «simplified» adaptability conditions. The stability of a closed control system is proved and the conditions for this are determined. For the current identification of load parameters, the recursive least squares method with a forgetting factor is used. This control method was developed specifically for research and debugging on an experimental layout, so all the parameters of the crane and load were approximated to the layout during calculations. The results of computer simulation the proposed control method with different mass-inertial properties of the load, the length of its suspension and perturbations in the Matlab Simulink software environment are presented. The results showed the high efficiency of the proposed adaptive control system. It ensures accurate movement of the load in a short period of time, prevents the load from swinging during acceleration and braking of the cart, and is also able to fend off external disturbances, for example, the impact of wind. The developed approach can be recommended for any crane installations using a suspended load.","PeriodicalId":273068,"journal":{"name":"Proceedings of Tomsk State University of Control Systems and Radioelectronics","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133240877","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}
