International IEEE Conference and Workshop: Óbuda on Electrical and Power engineering (CANDO-EPE)

作者： György Schuster Obuda University Budapest Hungary Department of Instrumentation and Automation Hungary Kando Kalman Faculty of Electrical Engineering Institute of Electronics and Communication Systems

As the complexity of tasks increases, developers have to use different tools. We talked about this in details in some previous publications. In this paper, we will touch on a special area that is increasingly coming to the fore these days, which is the question of the application of models. However, the application of models in safety-critical systems raises the question of the reliability of the models and the questions of the certification of these software tools.

This paper proposes a project to teach in a practical way several key factors of the Industry 4.0 technologies for electrical engineering students and teachers. The key factors are cibersecurity in industrial networks, industrial SCADA protocols and remote maintenance. Remote access to industrial networks is one of the contributions that Industry 4.0 has popularized because it makes industrial networks reachable using the public Internet. Remote maintenance is one of the great beneficiaries of this functionality. However, this access increases the security risks because a new and important vulnerability is opened by the access possibility from any computer connected to the Internet. To address this challenge, engineering students have to deal with industrial protocols topics, cibersecurity topics and control topics. This work presents an educational project to actively implement an atractive solution for remote access in industrial networks using open-source solutions. The selected open source solutions are the industrial telemetry protocol MQTT in the exchange of access control commands between the involved devices, the openvpn and ssh as a well-known VPN open-source product used for the remote access itself, the NodeRED platform as control dashboard and the IEC62443 industrial cybersecurity standard in order to monitor and audit the effectiveness of the project.

Manned/unmanned aerial team is potential to overcome the autonomy challenge in current unmanned aerial vehicle (UAV) swarm. This paper provides a heterogeneous system containing the cluster space formation control method and generalized homogenization control method. Three-dimension cluster space formation controller could reduce the operator workload through converting the swarm states variables to cluster space variables. The decrease of the operation times could bring lots of benefits to the UAV swarm formation. The utilization of the generalized homogenization controller guarantees the convergence of the system and helps the system converge to the desired states fast. Comparative experiments are conducted on numerical simulations in manned/unmanned aerial team to validate the robustness and superiority of the proposed cluster space formation approach with generalized homogenization controller. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

The share of renewable energy sources in the energy mix worldwide is gradually increasing. And even though they all have a highly variable nature, they can be forecasted statistically. The wind energy potential was investigated in this article in the Bulgarian Danube region, located between Ruse and Silistra. Two years of meteorological data, including the wind speed at 10 m height and the ambient temperature was used to estimate the average wind energy for each month of the year at three geographic locations - Ruse, Staro Selo (near Tutrakan), and Calarasi, Romania (near Silistra). The results showed that Staro Selo has the highest energy potential, reaching up to 0.75 kWh/day/m2 in February, followed by Calarasi with 0.38 kWh/day/m2. The city of Ruse showed the lowest wind potential with the highest average monthly value reaching only 0.0027 kWh/day/m2. The obtained results showed that the regions around Tutrakan and Silistra are appropriate for the application of micro wind turbines. © 2024 IEEE.

Event-triggered receding horizon control via actor-critic design

In this paper, we propose a novel event-triggered near-optimal control for nonlinear continuoustime systems. The receding horizon principle is utilized to improve the system robustness and obtain better dynamic control performance. In the proposed structure, we first decompose the infinite horizon optimal control into a series of finite horizon optimal problems. Then a learning strategy is adopted, in which an actor network is employed to approximate the cost function and an critic network is used to learn the optimal control law in each finite horizon. Furthermore, in order to reduce the computational cost and transmission cost, an event-triggered strategy is applied. We design an adaptive trigger condition, so that the signal transmissions and controller updates are conducted in an aperiodic way. Detailed stability analysis shows that the nonlinear system with the developed event-triggered optimal control policy is asymptotically *** results on a single-link robot arm with different noise types have demonstrated the effectiveness of the proposed method.

This paper proposes a concept for building an intelligent street lighting system by using different software and hardware components, allowing hybrid management of the intensity of the lighting fixture. With the proposed solution, streetlamps can be controlled remotely, both individually and in groups. The main idea is to receive online information about the status of each light fixture in a dispatch center and to control it remotely. © 2023 IEEE.

This paper is devoted to using Machine Learning methods to detect Marine Debris from other objects on the surface of the ocean. Data from the MARIDA dataset gathered over the years by the Sentinel-2 (S2) satellite was used. The aim is to recognize debris from other surface features, such as waves, ships, foam, etc. The paper compares two methods for marine debris detection. The decision tree and random forest methodologies were used.

Increasing digitalization in manufacturing, often associated with terms like Industry 4.0 (I4.0) or Smart Manufacturing, is a topic of crucial concern for manufacturing companies. Different digital technologies (DTs) can be integrated into manufacturing processes and systems aiming at increasing flexibility, product quality or productivity. The type and scope of potential DTs must be carefully selected when planning and improving a manufacturing system. The definition and configuration could be supported by simulation techniques that assess the DTs' impact on the manufacturing system and its final performance. However, parametrizing the DTs into a simulation tool is not straightforward since appropriate models might be challenging to obtain and actual impacts of DTs are uncertain. Against this background, the paper presents methods to enable a simulation-based assessment while considering the impact of not just individual but also a combination of DTs. The paper introduces a framework to define the base characteristics of selected DTs within a manufacturing system and their parameterization into a commercial simulation tool. Furthermore, the usability and expectable results are demonstrated in a case study. © 2022 The Authors. Published by Elsevier B.V.
