Integration of Simulator in AAS for Heat Transfer Station
Černocký, Petr ; Jirsa, Jan (referee) ; Arm, Jakub (advisor)
This work examines today's modern methods of production management, without which the entire Industry 4.0 phenomenon would not be possible. The main focus of this work is the Asset Administration Shell and the integration of models and simulations into it. Furthermore, research is carried out in the area of modeling and visualization of production and production processes, which is also provided with an example of communication between the visualization software UNITY and the calculation software Matlab. From the analysis, the most suitable software is also selected for the final implementation. Furthermore, there is a proposal for the integration of the simulator into AAS and then its practical implementation. At the same time, the entire designed system with an integrated simulator is evaluated here.

Modelica Models use in Matlab-Simulink Environment
Glos, Jan ; Blaha, Petr (referee) ; Václavek, Pavel (advisor)
This thesis solves the use of Modelica models in Matlab/Simulink enviroment. The first part is focused on Modelica language and Functional Mock-up Interface, a standard way for model exchange and co-simulation of dynamic models, which is supported by most Modelica oriented tools. Based on this standard FMUtoolbox was created and it provides the ability to import and simulate models exported as Functional Mock-up Unit. The tool provides a Simulink block, graphical and command-line interface.

Mathematical description of VRB battery
Korniak, Daniel ; Mastný, Petr (referee) ; Radil, Lukáš (advisor)
This work is in the introduction focused on the introduction of technologies for electrical energy storage, their description and capturing the main advantages and disadvantages. After this capture follows comparison of the various technologies in terms of efficiency , discharge time and the price for1 kWh . Following section focuses on electrochemical model VRB batteries , which describes the equations describing the behavior of a battery depending on the chemical an electrical properties . In the penultimate chapter, I introduced the language of object- oriented modeling language Modelica and the most common programs based on it, including a short introduction for modeling in MathModelica. The last part deals with the modeling of specific VRB battery, which we have at the faculty.

OpenModelica and Matlab-Simulink co-simulation
Szymanik, Adam ; Kozubík, Michal (referee) ; Václavek, Pavel (advisor)
This thesis solves co-simulation between OpenModelica and Matlab-Simulink. In the first part Modelica language, OpenModelica software and FMI standard are described. In the next part is proposal of solution through custom blocks and realization of those blocks. In last chapter are three examples to verify functionality of my solution.

Acausal modelling of termomechanical problems using Modelica
Shestakov, Andrey ; Elcner, Jakub (referee) ; Pokorný, Jan (advisor)
The aim of this bachelor thesis was the development of a library for solving thermodynamics tasks in Modelica. The library contains models of cycles working with both the ideal gas, and the real substances. The main part of the work is the description and modeling of Steam Rankine Cycle and Organic Rankine Cycle that are applied in Waste Heat Recovery (WHR). The working principle of both cycles is similar. The main difference is in the working fluid. In this work, we give a technical economical assessment of the application of ORC system in concrete industry for energy costs reduction. The change of ORC parameters with the choice of particular working fluid is the main task of the thesis. Based on the simulated model results for selected working fluids (water, Cyclopentane, Toluene, Heptane, R123 and R245fa), we concluded that the highest efficiency was achieved with R245fa refrigerant for Organic Rankine Cycle in case of selected initial conditions.

HIL model of electromechanical system
Malík, Lukáš ; Bartík, Ondřej (referee) ; Blaha, Petr (advisor)
This diploma thesis deals with creation of elektromechanical model in Modelica language which is subsequently imported into LabVIEW environment. The Modelica language, LabVIEW graphical programming tool and Functional Mock-up Interface 2.0 standard are described in the introduction of this thesis. Functional Mock-up Interface is a tool independent standard witch, defines a standardized interface to ModelExchange and Co-simulation of complex system components. The model of electromechanical system was created based on Functional Mock-up Interface standard. Part of the work focuses on the Functional Mock-up Unit storage possibilities and LabVIEW support to import models of this type. The imported model was simulated and tested in this environment. Finally, the instance of Functional Mock-up Unit was connected with LabVIEW FPGA target for the purpose of model HIL simulation on CompactRIO platform.

Risk Analysis of Self-Driven Vehicles
Weigel, Filip ; Šimek, Václav (referee) ; Strnadel, Josef (advisor)
The goal of this thesis was to design and implement system for risk analysis in self-driving cars. This thesis focused on design and implementation of system for risk analysis in models. One of the requirements for the system was to be flexible and robust. Design of the risk analysis was presented at theoretical level and then implemented in models of ABS and ESP systems in UPPAAL environment. The system was then tested via multiple experiments. The experiments were beneficial and the system for risk analysis correctly evaluated failure scenarios with adequate response to the rising level of risk. Experiment outputs were then presented at graphs with comment to each failure scenario.
