The article presents the development and experimental verification of a control system based on a highlevel controller by a group of unmanned aerial vehicles (UAVs) based on the ROS 2 framework and the PX4 autopilot in the Gazebo simulation environment. The system is designed to address challenges related to autonomous navigation, group coordination, and obstacle avoidance in complex environments. The modular architecture of the control system is described, which includes such components as a high-level controller, a Gcommand processing module, a flight control module, and a data visualization module. For modeling and testing the system, the Gazebo simulation environment is used Gazebo, which provides realistic physical modeling and integration with ROS 2. The results of modeling and experimental studies of the movement of a group of UAVs are presented, during which the correctness of command execution, coordination of the group of UAVs and the stability of the system to external influences are checked.

With the expansion of the power grid scale, the uneven distribution of power generation and load in the region, as well as the uneven distribution of power flow in transmission and transformation equipment, have become increasingly prominent. The problems of equipment overload and light load coexist, and are limited by the bearing capacity of overloaded equipment and the difficulty of fully utilizing the power supply capacity of the power grid. The UPFC is an advanced flexible AC transmission device that can solve the above problems through control measures. This article studies the strategy optimization technology and emergency voltage control technology of UPFC in supporting the operation of power ***, the effectiveness and correctness of the proposed method are verified through a practical example of power grid calculation.

This paper focuses on the diagnosis of electrical faults in electrical drives based on the permanent magnet synchronous machine (PMSM) which is supplied by a system of voltages delivered by a voltage inverter, this is controlled by the hysteresis strategy with three reference currents. High current or cut-off can cause problems for three-phase equipment and the most common impact of these faults is overheating of the equipment and consequently degradation of electrical insulation and reduction of service life. A modeling of the system performance in the healthy and faulty machine cases has been simulated. In this paper, firstly, the system is analyzed for the different supply current faults of types: unbalance and current break. Then, the fault detection of the permanent magnet synchronous machine can be illustrated by the evolution of the parameters that describe the electrical and mechanical characteristics of the machine. The results of the simulation are realized by Simulink MATLAB.

The integration of intrusion detection systems (IDS) is crucial for strengthening network security. Improving IDS performance requires advanced techniques for handling intrusion detection data, with machine learning playing a key role. However, machine learning methods often face difficulties in detecting complex attack patterns and are prone to generating a high number of false positives, especially when dealing with unknown attacks. To overcome these issues, enhancing IDS capabilities with knowledge graphs is essential. Knowledge graphs have proven to be valuable tools for modeling and analyzing complex interactions within security data. This article proposes an approach that combines knowledge graphs with machine learning and deep learning. By harnessing the semantic modeling, querying, and reasoning capabilities of knowledge graphs, this integration aims to address the challenges of intelligent detection and decision-making in cybersecurity.

In this study examine the interaction of three objects, each with the potential to disable the others with a certain probability. The dynamics of the probabilities of the system states, as well as the limiting case, are investigated depending on the values of these probabilities. In the case of two objects, an analytical formula is obtained. In the case of three objects, a numerical model is created. Additionally, for three objects, the possibility of recovery is considered, taking into account the cost of finite resources.
