HAM-Tools library use for the simulation of the thermal performance of the house
Zábojník, Jakub ; Charvát, Pavel (referee) ; Štětina, Josef (advisor)
In terms of master’s thesis HAM-Tools library designed for MATLAB/Simulink was modified for the use in simulations of houses in the Czech Republic. Modified library and its parts were described in detail and tested by the simulation of the one-zone and two-zones models of the house. The simulations of models with same parameters were also realized in program TRNSYS. The corresponding results achieved in mentioned simulation tools were compared to each other. The one-zone model created by using HAM-Tools library is tested by the simulation of ventilating, heating, cooling, and sources of moisture. A demonstration of the practical use of the simulation is carried out in the thesis, namely by examining the influence of the insulation thickness on the thermal performance of the house (resp. its heat loss) on real atmospheric conditions. Among others, available resources of meteorological data are mentioned and compared to each other. The function for processing of the meteorological data to a file compatible with the HAM-Tools library was created. It was also created a material data file containing commonly used materials of building structures in the Czech Republic and their parameters.

Optimal control of a wind power plant
Paděra, Zdeněk ; Veselý, Ivo (referee) ; Zezulka, František (advisor)
The thesis first provides a brief introduction to wind energy and bring in the current status of this rapidly growing industry. Further, the distribution of wind turbines, their specific and general description of the construction is described. Emphasis is placed on wind turbine control system. The first goal was to build a simulation model of wind power plant in the MATLAB / Simulink usable for subsequent overall design of control system of wind power plant. Furthermore, the analysis of the control of individual components of power station in the light of the possibility of optimizing the operation and in particular the optimization of efficiency of plant, i.e. maximization of the reached performance is performed. In the last part of this thesis structure and parameters of individual control system of plant is designed and the results are discussed.

Simulation of the Drive with Synchronous Machine and its Evaluation using a Real System
Tkadlec, Josef ; Veselý, Libor (referee) ; Václavek, Pavel (advisor)
Práce se zabývá modelováním PMSM, jeho parametry a jejich získáváním. Dále je v práci popsán model měniče beroucí v potaz dead-time efekt. Tyto modely jsou implementovány společně s dalšími bloky v prostředí Matlab/Simulink a dohromady tvoří knihovnu pro vektorové řízení motorů FSL_MC_TOOL. Součástí práce je také měření a identifikace parametrů skutečného PMSM. Dále byly vytvořeny příklady simulací, v nichž je použit motor s těmito parametry a vyhodnocena přesnost simulace. Tímto jsou simulace ověřeny na reálném systému.

Electromagnetic energy harvesting resonator for train trackside
Rusková, Miroslava ; Singule, Vladislav (referee) ; Hadaš, Zdeněk (advisor)
The aim of the diploma thesis was to design an electromagnetic generator to the purpose of supplying signalling and safety devices on the rail tracks. The electromagnetic generator is a separate electrical source, which is mainly needed for safety in the case of not covered tracks by electrical installation. The thesis proposes two types of electromagnetic generator and one with non-linear stiffness, which are designed for the passage of trains with low frequency.

Design of electromagnetic laboratory shaker
Vaněček, Michal ; Březina, Lukáš (referee) ; Hadaš, Zdeněk (advisor)
My thesis describes the design of a laboratory electromagnetic vibrator, which will be used for testing of the vibrating microgenerators. In the first part of my thesis is the search of selected laboratory electromagnetic vibration generators. There is also formulated its own proposal and subsequent tuning of the required dimensions and characteristics of the laboratory electromagnetic vibration generator. The tuning of necessary properties and dimensions is formed as modeling and simulating in programms Matlab / Simulink and ANSYS. The conduct of laboratory electromagnetic vibration generator is implemented in MATLAB / Simulink. Design and dimensions of the laboratory electromagnetic vibration generator is made in SolidWorks.

Active Vibration Damping/Chatter Control of Machine Tool Spindle Units
Škúci, Michal ; Blecha, Petr (referee) ; Březina, Tomáš (advisor)
This bachelor’s thesis describes the issue about machining, causes of spindle chatter and different ways of chatter damping. It evaluates advantages and disadvantages of different ways of damping. There was made and described simple simulation model on which searching simulations was made for purpose of receiving picture of behaviour of model for different parameters. Model of active damping was made too.
