Optimization of CNC milling machine axis movement
Blaško, Dávid ; Lang, Stanislav (referee) ; Poliščuk, Radek (advisor)
The aim of this thesis is to analyze current state of the device, which is robotized CNC milling machine OPTIMUM BF20L, driven by B&R Automation hardware. The theoretical part describes the possibilities of a machine construction and its elements related to the machine’s movement, possibilities of generating a tool path for CNC, their usage and associated advantages and disadvantages. The goal of the study was to improve the dynamic characteristics of axis movement, and the resulting tool movement during its transitions and rounding, considering the clearance in machine design and its components.

Optimized Power Factor Compensation Using Capacitor Banks
Kseňak, Ján ; Hammer, Miloš (referee) ; Poliščuk, Radek (advisor)
The aim of the thesis is the design of a power factor controller for the power grid, including HMI. The theoretical part of the thesis is divided into two logical units. The first unit explain the problem of power factor correction in a linear electrical environment, without considering harmonic distortion. The second theoretical unit describes the technologies, applied in cooperative simulation environment. A virtual commissioning of the whole system was performed in the simulated environment. The empirical part of the thesis describes the architecture of the Mosaik simulation framework. Then folows description of the controller, its integral components and the HMI. In the last chapter, the whole system was put into virtual operation, in order to perform function tests. The controller was tested on change of the power factor setpoint and to test the reaction on system change, without losing the power factor compenation.

Modeling of machinery in Matlab/Simulink and Simscape
Moravanský, Lukáš ; Poliščuk, Radek (referee) ; Lang, Stanislav (advisor)
The thesis focuses on the development of a digital twin of the axis of the mould cylinder of a flexographic printing machine for SOMA using MATLAB/Simscape software. Theoretical foundations and concentrated parameter methods were used to develop and validate the physical model, with the main focus on the accuracy of the match with the real system in terms of resonances and aniresonances. A graphical user interface (GUI) was developed to allow easy modification and testing of the model. The work demonstrates the benefits of linking MATLAB tools for developing physics models and provides a basis for future model modifications and extensions.

Modern approaches in the analysis and evaluation of vibrations in machines and equipment
Mikuš, Juraj ; Poliščuk, Radek (referee) ; Hammer, Miloš (advisor)
The thesis focuses on modern approaches in technical diagnostics. As a part of the implementation, an online monitoring system SIPLUS CMS1200 was programmed. The measured data were transferred using the FTP protocol to a local server. The analysis of the measured data was conducted using CMS X-Tools software. The result of the work is a functional monitoring system that continuously monitors the machine's condition while keeping the operator informed about the current state of the monitored variables. This system helps to prevent unplanned downtime and also financial losses.

Google Wave Technology
Michlík, Pavel ; Krček, Petr (referee) ; Poliščuk, Radek (advisor)
The Master’s thesis explains API and features of Google Wave technology, which was designed for flexible real-time collaboration of defined participants. The project aim was description of Google Wave basic elements and creation of sample Wave extensions, demonstrating capabilities of the communication protocol. The first extension (robot) was developed using client libraries in Java. The second extension (gadget) shows another approach of Google Wave extensions, based on XML, HTML, CSS and JavaScript.

Tool for easier automation visualisation creation in mapp View technology
Kseňak, Ján ; Lang, Stanislav (referee) ; Poliščuk, Radek (advisor)
The aim of the bachelor thesis is create a program that will simplify development of automation visualizations using mappView technology in the development environment B&R Automation studio. The theoretical part of thesis contains more detailed description of mappView technology and its necessary components. At the beginning of the practical part is mentioned a selection of technologies that were used in development of the application, which should simplify development of mappView visualizations. Furthermore, in the practical part, we describe the architecture of application, the process of creating application, the design of a graphical user interface of application and the integration of application in the development environment B&R Automation studio. The last chapter shows the whole process of developing mappView visualizations in the development environment B&R Automation studio and the use of application in this process.
