Modeling and control of rear driven axle for Formula Student
Kavec, Matúš ; Veselý, Libor (referee) ; Pohl, Lukáš (advisor)
This thesis is focused on design of controll structure of Formula Student monopost. Part of the thesis is a design and subsequent debgging ofthe model so it has the best possible response compared to reality. A PID controller with two degrees of freedom was used to create the control structure. Created controll structure has the task of regulating the system to the required value. By reducing skid, which is often unwanted in race cars, we can achieve better response while accelerating.

Models of DC transistor converters in Simulink program
Loup, Martin ; Pazdera, Ivo (referee) ; Huták, Petr (advisor)
The master’s thesis is focused on the creation of models of DC/DC converters and control program for input parameters and their configuration. The first part is theoretical and she is dedicated to the description of the program Matlab. The second chapter is dedicated to DC/DC converters. Their function is described there and the necessary equations for the design are derived. All of this is complemented by the calculation of line losses in semiconductor elements and the design of voltage and current regulator. The last two parts deal with the description of the created models in Simulink and control program in a graphical environment. The created program is able to edit and recalculate parameters of the converters, calculate line losses on semiconductor components, perform a model simulation or open it.

Modeling of Dynamics of the Part of a Printing Machine
Junek, Jiří ; Šolc, František (referee) ; Václavek, Pavel (advisor)
This thesis deals with modeling dynamics of printing machine, made by SOMA Engineering, in toolbox SimScape of simulation program Simulink/Matlab. There are descibed properties, progress, important principles and laws of modeling in this toolbox. The first part is focused on creating models, which consist as mechanical as eletrical and control parts. In the second part is explained how to create user interface to control models and creating standalone application, executable without installation of Matlab or Simulink. In last part is explained principle of identification parameters of material from the measured data, using an optimalization algorithm Nelder-Mead. Created models and identification algorithm are controlled via user interface.

Condition monitoring of mechatronic systems
Horňan, Bohdan ; Buchta, Luděk (referee) ; Blaha, Petr (advisor)
This thesis is concerned with condition monitoring and quantitative analysis of synchronous motors. Constantly rising requirements on the reliability of motors develop new methods of predictive diagnostics, which can identify failure conditions in the initial stage. Created mechatronic systems with the implemented failure from pre-prepared PMSM model are tested by unconventional condition monitoring methods. Software solutions of diagnostics and model designs of the mechatronic systems are implemented in MATLAB & Simulink. Part of this work is also a short introduction to the issue with necessary theoretical fundamentals and research of some selected methods of predictive diagnostics.

Development of database of mechatronic models in Simscape
Al-Dailami, Zaid Abdulqudos Abbas ; Najman, Jan (referee) ; Bastl, Michal (advisor)
Tato práce se zabývá především vývojem databáze modelů mechatronik v nástroji Simscape. Je rozdělena do tří hlavních částí a to následně: První část popisuje nástroj Simscape a jeho možnosti . Práce poskytuje návrh, jak nastroj použít při vývoji modelů a jak se liší od jiných způsobů modelování. Druhá část obsahuje některé mechatronické modely založené na Simscape. Některé z modelů jsou také vytvořené pomocí standardního modelování Simulinku, a ty lze porovnat s dříve uvedenými modely. Třetí část je zaměřena na jeden z dříve navržených modelů se stejnosměrným motorem. Tento model se používá k vyhodnocení, odhadu a optimalizaci skutečných parametrů stejnosměrného motoru, obsahuje také popis, jak vygenerovat c kód z modelů Simscape, abychom jej použili v HIL.

Matlab Models of DC/DC Converters
Macík, Tomáš ; Cipín, Radoslav (referee) ; Pazdera, Ivo (advisor)
The Bachelor’s thesis is focused on modeling of DC/DC converters without a transformer using Matlab Simulink software. The first part is dedicated to general explanation of function of selected switch mode power supplies. The second part contains the deduction of equations for every selected switch mode power supply and design of circuit components based on required converter parameters. The models of converters have been created in Matlab Simulink using deduced equations. The models of STEP UP and STEP DOWN converters have been created also using Simscape Power Systems Toolbox and the control of current and voltage has been designed for them.

Room Temperature Advanced Control Algorithms
Glos, Jan ; Graf, Miroslav (referee) ; Václavek, Pavel (advisor)
This bachelor's thesis deals with constructing a thermal model of the specific room and algorithms design for heating and air conditioning. The model is created using Simscape extension for Matlab/Simulink and is based on real attributes of room and its walls (materials, dimensions etc.). This thesis contains design of MPC (Model Predictive Control) and PI controllers. In comparison with the original regulation designed controllers achieve better quality of control and MPC controllers seems to be the best. Because of preliminary for integration of split air conditioner, possibility of control actuators by MPC controller and because of necessary setpoint separation (for heating and air conditioning) software equipment of the individual zone controller was revised.

Magnetic field calculating of transformer by using conducting model
Bláha, Martin ; Skalka, Miroslav (referee) ; Kurfűrst, Jiří (advisor)
The paper deals with conductivE-resistive network. Use of this network is modeled transformer. The model is implemented in simulation program PSPICE and Simscape. To evaluace the results were used the values obtained using the finite element method. A simple model of the transformer has been replaced by rezistor network conductivity, which is divided into elements. According to these elements is a simplified model designed and analyzed
