The use of software tools and applications progressively became a standard in both education and industry. A solution for hand-drawn electrical scheme digitization has been proposed to match the fast-paced dynamic of the modern world in the field of electrical engineering. The aim is to notably reduce time-consuming and error-prone electrical scheme tracing from hand-drawn to simulating software. The means have been achieved through the usage of state-of-the-art deep learning model YOLOv5 for electrical elements detection along with Python and OpenCV library for data processing. The user’s input is an image of a hand-drawn circuit, and the end result is an LTspice digitized electrical scheme ready for simulation.

This paper studies the lateral and longitudinal formation control issue of a collection of vehicles subject to wear and road disturbance. A novel prescribed-time disturbance observer is designed to estimate the unknown disturbance. Then, based on the disturbance observer, an adaptive nonsingular vehicle formation control strategy is proposed to ensure the formation errors converge to a close neighborhood of origin in a prescribed time, which can be confirmed in advance by specifying several simple parameters. Simulation results validate the effectiveness of the presented control method. © 2024 Technical Committee on control Theory, Chinese Association of automation.

To enhance the robustness of the permanent magnet synchronous motor(PMSM) speed control system, and reduce the response time of the control system, a composite terminal sliding mode control strategy is proposed. Firstly, a integral terminal sliding surface and a fast reaching law are designed based on the mathematical model of the PMSM to avoid singularity issues,enhance quickness, and reduce chattering. Then, the stability and finite-time convergence of the control system are proved by constructing a Lyapunov function. Considering the system's susceptibility to disturbances, the lumped disturbance is considered in the mathematical model. An extended state observer(ESO) is designed to observe the lumped disturbance and compensate for the lumped disturbance to the controller. Finally, through simulation and experimentation, it is demonstrated that the designed controller exhibits advantages such as fast response, no overshoot, and strong robustness.

Continuous in-line identification of magnetic properties of ferromagnetic steel strips is developed and investigated. It is demonstrated that estimates of the magnetization curve of the strip material can be made if the operating frequency of the induction heating (IH) system is known. In particular, the nonlinear function of the effective magnetization curve (effective $B-H$ curve) of the strip material is estimated by a moving horizon estimator (MHE) when heating the strip in the IH furnace. The magnetization curve is modeled using a linear and an exponential function and parametrized by two parameters. The MHE is based on frequency measurements and the current power of the electric supply circuit. The complex coil impedance derived from a distributed-parameter formulation of time-harmonic Maxwell's equations is used for the frequency calculation. It is shown that if the strip is insufficiently excited, the estimation of the parameters of the effective $B-H$ curve becomes inaccurate. Therefore, the possibility of a non-uniform power distribution of a supply circuit with two power inverters was analyzed. As a main finding, it is demonstrated that the estimation accuracy can be significantly improved if the local strip excitation can be increased. It is also proven that a suitable unequal power distribution does not change the strip exit temperature compared to a uniform power distribution. The estimation results are validated in a scenario for a steel strip with the effective $B-H$ curve known from laboratory measurements.

The article deals with the choice of criteria for efficiency, applicability in measuring technology, analytical and construction, on the basis of which a methodology for assessing the quality of structures of measuring devices of moisture of materials of the agro-industrial complex is proposed. The standard deviation of the random error characterizing the accuracy of measurements is shown. A complex efficiency criterion is discussed, including the dominant particular parameters: accuracy, reliability, cost, allowing to solve the problem of optimal design of humidity control devices for the materials under consideration. As an optimal option, a differential measuring device is analyzed, which practically eliminates random and systematic errors and makes it possible to design a multiparameter measurement method that considers the features of a heterogeneous environment, such as bulk grain materials of the agro-industrial complex © 2022 IEEE.

Information and communication technologies have become an integral part of modern society in Uzbekistan, as they are used in all spheres of human life: economic, political and social. Uzbekistan is one of the countries where digital technologies are rapidly developing, because of which significant results have been achieved in education. The expansion of distance education will improve the quality of education, because more students who live in rural areas are covered. This will allow you to receive high-quality content (video, audio, and platform);use the most up-to-date technologies and solutions: online services for the educational process, gamification, a virtual library, online proctoring and practical online classes. Interactive learning is a learning process using information and communication technologies. Although distance learning is not a substitute for university attendance, it is an excellent learning tool for consolidating knowledge and obtaining additional facts and information. Sometimes homework is not enough for proper understanding and assimilation of educational material. Proper understanding of information is useful for practical subjects. The Internet provides a wide range of such additional features. Interactive stands enhance both general and professional knowledge;have a motivating effect on learning in a playful way. The National Research University in Uzbekistan, together with the teachers of the Tashkent State Pedagogical University, is actively working on the introduction of virtual interactive educational stands into the educational process, including distance education. The computer program provides for the implementation of training lessons in the section 'Logical foundations of computing systems', namely 'Representation of functions of the algebra of logic', 'Minimization of logical functions by the Veitch diagram method', 'Minimization of logical functions by the Quine method' © 2024 IEEE.

In the continuous hot-dip galvanizing process, the final zinc coating thickness is heavily influenced by the distance between the strip surface and the gas wiping dies which blow off excess zinc. To this end, establishing a flat, non-curved strip is a key prerequisite to minimize coating thickness deviations and inhomogeneities. A common way to influence the lateral strip profile is to introduce a controlled plastic deformation of the strip at the guiding rolls in the zinc bath. This motivates a data-based study of the optimal roll intermesh value of the zinc bath rolls to achieve a flat (zero-crossbow) strip profile during the galvanizing process. Based on this analysis, a data-based algorithm for the online prediction of the optimal roll intermesh value at the head end of each strip is developed and implemented in an industrial processing line. The prediction results from 1045 strips demonstrate the feasibility and accuracy of the proposed prediction algorithm.

Iterative learning control (ILC) is excellently applied to output tracking for systems that perform repetitive tasks. Classical norm optimal ILC (NOILC) approach yields optimal control inputs by minimizing a quadratic cost function. However, this approach requires the introduction of supervectors, i.e., lifting technique, for system description, which raises a high computational load problem. The contribution of this paper is to propose a non-lifted NOILC (N-NOILC) approach by redesigning a cost function that does not involve the lifting technique, achieving the goal of efficient computation. Therefore, the proposed approach is particularly suitable for large tracking tasks with long trial duration and high sampling frequency. Moreover, considering the model uncertainty in practice, robust convergence is analyzed. Numerical simulations are shown to demonstrate the properties and advantages of the proposed approach. © 2024 IEEE.
