The energy crisis is a massive problem in today's world. Conventional energy sources are not only limited but also major contributors to environmental pollution. Renewable energy sources are becoming priorities worldwide. To reduce dependence on conventional energy sources, it is necessary to explore alternative options. Solar energy is rapidly gaining attention as an important means of expanding the use of renewable energy. Solar cells, which convert solar energy into electrical energy, are expensive and relatively inefficient. Various mechanisms and systems are used to increase the efficiency of solar cells and maximize energy generation. A solar tracking system is used to enhance the efficiency of solar cells by tracking the movement of the sun. This article describes the methodology for designing an automatic solar tracker based on the ESP32 microcontroller. Light-dependent resistors (LDRs) are used as sensors to detect the current position of the sun. The proposed tracker has a precise control mechanism that adjusts the orientation of the solar panel based on the measured values from the LDRs to achieve the optimal position perpendicular to the sun, ensuring the highest productivity in energy generation. The result is a constructed small-scale prototype of a solar tracking system, along with a description of its components and the programming part.

This paper presents client-server mobile system for diagnosis of asynchronous motors. The system is created as a mobile application for smartphones and tablets. The system provides processing of the measured values of the currents and voltages of the stator phases of the asynchronous motor. According to the processing results, the results of diagnostics and forecasting of the current state of asynchronous motors are calculated. The software runs on the Android OS. The main purpose is to predict the current state of AD, which has a parametric electromagnetic asymmetry of the stator phases.

In this paper, facing the aerial transportation task with a large volume cargo, the system of quadrotor with a cable-suspended rigid payload is investigated. The dynamic model of proposed system is built with Lagrange d’Alembert principle. The dynamic model is linearized to design the feedback control method. Finally, two groups of numerical simulation with proposed feedback controller are designed to demonstrate the effectiveness of system model and the results of simulation illustrate satisfactory performance.
