This paper is dedicated to the development and research of the advanced approach for optimization of fuzzy control systems (FCS) for mobile robots (MR) with remote control based on bioinspired swarm techniques. The proposed approach makes it possible to create effective intelligent control systems for MRs based on the principles of hierarchical multi-level control, remote IoT-based control, fuzzy logic control, and intelligent optimization of fuzzy control devices. The applied hybrid particle swarm optimization (PSO) techniques with elite strategy allow effectively optimizing various parameters of FCSs, finding the optimal solution to the problem, and, at the same time, have a higher convergence rate compared with the basic PSO algorithms. To evaluate the effectiveness of the obtained advanced approach based on hybrid swarm techniques, the optimization process of the FCS for the speed control of the multi-purpose caterpillar MR, which can move on inclined and vertical ferromagnetic surfaces, is carried out. The presented research results fully confirm the high efficiency of the proposed approach, as well as the expediency of its application for the optimization of fuzzy control systems for various remotely controlled mobile robots. © 2023 River Publishers.

The problem of constructing a mathematical model for the Internet transport protocol based on additive increase and multiplicative decrease in window sizes for receiving a message flow in a router is considered. In the course of the study, a mathematical model of a TCP-friendly protocol was obtained in a new form, represented by a linear regression equation. The adequacy of the model is shown based on the known representation of the transport protocol by the system of differential equations and its representation by units in Simulink Matlab and by comparing the numerical results of the models. © 2022 IEEE.

A Mobile Application of a Decision Support System for Ballasting a Floating Dock

Journal of Mobile Multimedia 2024年第3期20卷 597-626页

作者： Topalov, Andriy Kondratenko, Yuriy Shevchenko, Anatolii Zaytsev, Valeriy Kozlov, Oleksiy Zaytsev, Dmytro Golikov, Volodymyr Computerized Control Systems Department Admiral Makarov National University of Shipbuilding Mykolaiv Ukraine Intelligent Information Systems Department Petro Mohyla Black Sea National University Mykolaiv Ukraine Institute of Artificial Intelligence Problems of MES NAS of Ukraine Kyiv Ukraine Design Bureau IMT LLC Mykolaiv Ukraine National University “Odesa Maritime Academy” Odesa Ukraine

This paper is devoted to increasing the automation level of docking operations through the development of a mobile application for a decision support system capable of determining the optimal option for loading ballast into floating dock compartments when setting up and launching ships. The proposed decision support system and the mobile application allow implementing effective ballasting of the floating dock before docking the ship based on mathematical calculations of the impact of the ship on the floating dock and the ballasting rules. To test the developed system, the paper presents the functioning of the mobile application for a case of calculation of the docking up process of a 4, 100-ton ship. In particular, the load forces of this ship are calculated with a graphical display of the distribution of the influence of 20 sections of the ship on 6 pontoons of the floating dock. As a result, this decision support system with the implemented mobile application has the characteristics of a convenient interface and is easy to operate. It can provide the dockmaster data and suggestions for decision-making, and during its operation, it is actively replenished with a database of the docked up ships. © 2024 River Publishers.
