The problem of synthesizing effective laws of pneumatic drive control, which have adaptive properties to external disturbances, is quite urgent. It is quite obvious that in real operating conditions the control system will be affected by some external disturbing factors, the action of which can significantly rej ect the desired change in the controlled value. The purpose of this work is to develop an adaptive nonlinear synergetic control law for suppressing the disturbing effect, which was specified and additively introduced into the mathematical model in the form of certain mathematical functions. The synthesis of the adaptive control law was carried out using the method of integral adaptation, which is part of the concept of synergetic control theory. The obtained results of computer modeling confirm the adaptive properties of the obtained nonlinear synergetic control laws and the achievement of the set technological control goal - moving the rod to a given position under the conditions of disturbances.

The results of the development of an approach for the robust pole assignment based on the fulfillment of the Rouche's theorem conditions for a linear time-invariant single-input single-output system with system matrix parametric uncertainty and full-order state observer-based modal control are presented. The proposed approach allows to determine the minimum value of the geometric mean root of the desired characteristic polynomial of a system with a modal controller for given types of polynomials of a system with a modal controller and an observer, as well as the ratio of the roots values of these polynomials and a characteristic index determining the shape of the pole scatter domain, its size and location relative to the imaginary axis, as well as the minimum achievable dynamics performance, at which bounded parametric perturbations of the system matrix do not bring the poles of the closed-loop system beyond the boundaries of a certain domain of the complex plane.

The complex task of control of multiple configurations of documents, diagrams and code in the student projects in e-learning process requires a project management software tools. This paper presents the developed technology for managing course design, based on a sequential workflow and registration of the states of its stages. The design of a software tool that implements the proposed approach, data model and technical solutions used in the implementation is described. The flexibility of the developed tool is achieved by specifying a list of project stages and states in a local database. Change management is supported by the formation of a chain of messages, version control is based on sequential numbering and is fully automated.

Among the most difficult computer vision tasks is one of detecting object's action. Solving that problem, it is needed to be aware of the position of the key points of a particular type of an object. Information about key points position uses to management decision making in technical systems. It is also being complicated task with the fact that training models able to detect the key points require a significant amount of complexly organized data. This paper focuses on finding a solution to the problem of detecting the position of biological object key points. That information is useful in terms of object's actions classification as well as for tracking them. Due to the lack of data for training, a method for obtaining additional data for training is suggested (data augmentation), also various types of backbone models are tested within the R-CNN networks on differently augmented data, with different optimizers, learning rate, number of training epochs and batches. Achieved accuracy on the test sample is more than 90%. The use of backbone models of the ResNet family allowed to achieve greater accuracy of work, which was more than 93%, while the use of reference models from the MobileNet family with an accuracy of about 90% allowed to achieve a processing speed of each frame three times higher (on average) than while using backbone models of the ResNet family.

The internal nasal valve (INV) is one of the main causes of the nasal airflow obstruction. Minor changes in the cross-sectional area of the nasal valve region may have a significant impact on airflow, which in turn affects nasal function and the perception of airway patency. In recent years, the measurement of INV based on CT data has been widely used, but not all patients can be promptly performed CT. 111 patients who underwent endonasal surgery from September 2018 to January 2020 measured the cross-sectional area of the internal nasal valve and sphenoid sinus ostium using a new method. In all cases, we used the mobile application. The medium cross-sectional area of the internal nasal valve prior to septoplasty was 20–40 mm2, In the long term, we used this mobile App to measure the cross-sectional area and estimate the increase in the area after procedures. It easily showed a dynamic for sphenoid sinus ostium obturation. The new mobile App proved to be a fast and easily performed method. This application is useful for determining the cross-sectional area as well as to analyze this area in the dynamics.

The publication is devoted to the development of a model and research of the hydroelectric unit of a power plant with a Kaplan turbine. Matlab/Simulink environment was used for modeling. The main problems, features and approaches to the modeling of hydraulic units are discussed. The specificity of the proposed model is to take into account the nonlinear characteristics of the system and the influence of a synchronous generator operating on a bus of infinite power. It makes it possible to study the operation of the system in a wide range of modes. Equations and block diagrams of the main subsystems of the hydroelectric unit are given. The issues of adjusting the controllers of the hydraulic unit are considered. The graphs with the research results are presented and analyzed. Conclusions about the effectiveness of the obtained model are made and further ways of research are outlined.
