Design of linear external excitation drive with oscillative motion
Gärtner, Jan ; Kalous, Jaroslav (referee) ; Singule, Vladislav (advisor)
This thesis deals with design of linear external excitation drive with oscillative motion. In the first part of the work is shown describe types of linear motors. Further is a part of analysis of concrete linear drives from patents database. In the next part of this work is straight design of linear external excitation drive with oscillative motion. The conception in-clude geometric model created with software Solidworks, calculation of forces with software Ansys and dynamic models of mechanical and electrical part of drive with software Mat-lab/Simulink. And is a mentions possibility of controls of this drive too.

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.

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.

Dynamic analysis of oscillations with multiple degrees of freedom
Schulmeister, Jiří ; Houfek, Lubomír (referee) ; Březina, Lukáš (advisor)
This thesis is dealing with analysis of oscillating with multiple degrees of freedom and with example of dynamic behavior of system with two degrees of freedom with different input signals for purposes of dynamic lessons. Conventional method of making equations of motion by Lagrange’s method and their consecutive analysis is inscribed in the work. As example of system with two degrees of freedom is chosen quarter car model. Responses to different input signals are shown for the model. It is made in MATLAB/SIMULINK.

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.

Modelica Models use in Matlab-Simulink Environment
Glos, Jan
Acausal modeling is one of the approaches to construct a dynamic model of physical system. This approach is used by Modelica language and provides some advantages compared to causal modeling. Functional Mock-up Interface defines a standard way for exchange or co-simulation of dynamic models and is supported by most of Modelica oriented modeling tools. Matlab-Simulink is not able to use Modelica models nor to import Functional Mock-up Units. This paper describes FMUtoolbox for Matlab-Simulink, which allows simulation of Functional Mockup Units in Matlab-Simulink environment. It provides Simulink block, graphical and command-line user interface and other features
