Alternative control SW for dedicated thermal performance chambers with customized UI
Žlebek, Jan ; Veselý, Libor (referee) ; Václavek, Pavel (advisor)
This thesis is oriented on simulating thermal chambers, their SW and HW and improving SW to meet specifications. Testing problematics connected with this thesis is briefly mentioned also. Thermal chambers used here are dedicated to run simulating test procedures for thermostats and similar devices designed to sense temperature and regulate it. Design and realisation of new SW are clarified in latter chapters of this thesis, as well as evaluating functionality and resulting dynamics and accuracy.

Real Time Dynamic System Control
Adamík, Pavel ; Kaluža, Vlastimil (referee) ; Kunovský, Jiří (advisor)
This thesis focuses on the methodology of controlling dynamic systems in real time. It contents a review of the control theory basis and the elementary base of regulators construction. Then the list of matemathic formulaes follows as well as the math basis for the system simulations using a difeerential count and the problem of difeerential equations solving. Furthermore, there is a systematic approach to the design of general regulator enclosed, using modern simulation techniques. After the results confirmation in the Matlab system, the problematics of transport delay & quantization modelling follow.

Design of the Differential Test Rig for Testing in Anechoic Chamber
Ivanič, Michal ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
The diploma thesis describes the design of a test stand for experimental determination of vibroacoustic parameters of a part of the powertrain system. Thesis contains a research part, describing the problems of the drive system, vibroacoustics, measuring devices and also the division and the description of test stands. At the same time, the reasons for choosing a closed loop test stand are explained. Thesis also includes the results of analytical calculations and numerical results of FEM methods performed using ANSYS software, as well as drawing documentation of individual parts.

Closed loop system identification
Piskoř, Dominik ; Buchta, Luděk (referee) ; Pohl, Lukáš (advisor)
This thesis deals with testing of various modifications of the least-squares method, which reduces the bias in system parameter estimation. The first part of this thesis is focused on the theory and principles of every single method. The second part describes the implementation of identification methods in Matlab and Simulink. The third part is focused on the evaluation of used methods via statistical analysis. This part also contains an identification of electric parameters of the real PMSM motor model.

Řízení krokového motoru v částečně uzavřené smyčce
VEBER, Jan
The goal of this bachelor thesis is to clarify drivers basic of electric driver to students interrested in motion and some extended methods of control stepper motors with microcontroller. This thesis should explain principles of stepper motor, kinds of motion profiles, their properties, advantages, disadvantages and also methods their computations. Second goal is to explain the fieldbus protocol MODBUS and its implementation into PIC32 microcontroller. Practical part of this thesis is design and construction of a demonstration kit which allows to students see and better understand basic of stepper motor control and its integration to master system via MODBUS. Benefit of this thesis is that it introduce nowadays methods of control stepper motors to student to get view of industry implementation as well as control systems via fieldbuses/networks. The demonstration kit helps to achieve this goal. It was designed to be crash resistant, easy control and safe for users. The demonstration kit could be controlled by a third party device because of its modularity. Moreover the kit should be controlled by a PC software via MODBUS.

Analysis of modern payment methods
Klimeš, Martin ; Matuštík, Ondřej (advisor) ; Veber, Jaromír (referee)
This bachelor thesis is focused on the modern payment methods, which has nowadays became one of the most popular and used form of paying. The aim of this work is to formalise an analysis of modern payment methods and define its factor of successes. The bachelor thesis is being divided into several chapters. The first chapter is sourced from (available) written literature, highlighting the main definitions, focusing on the given topic in general but also briefly describes the historical points of view on it and the theoretical methods of critical success factors. The next chapter describes payment methods, which are being used nowadays, then focuses on the analysis of payment methods it self. Methods that are new, modern and innovative in different forms. Each method gives the basic information, function, security, typical situation and advantages and disadvantages of different forms of modern payment methods. Through this analysis we can determine the factors of success of payment methods and creates a discussion, which will result into a summary of factors that should improve and help with the development of the new payment methods. The last chapter contains selected forms of payment methods tested in real conditions.
