Design and construction of automatic galvanic line
Vondruš, Jiří ; Janda, Marcel (referee) ; Melichar, Petr (advisor)
This thesis deals with the design of automated system of electroplating. The first part is centered on designing the technological process for this electroplating and the setout of operating vats. It also deals with the project of mechanical construction, electrical system, with the computing procedure and the optimum choice of gear for galvanic line model. The work includes the design of a DC motor controller, the computing procedure and the construction of heating element for vats heater simulation. The last part of this thesis offers an insight to the control system and the assembled program. In the addendum, the photo of the realized model, the wiring scheme, and the programme transcript for control galvanic line model can be found.

Design of control units for semiautomous convoy
Kolomazník, Vojtěch ; Růžička, Michal (referee) ; Mašek, Petr (advisor)
This bachelor thesis deals with a design of a low level control units for a semiautonomous convoy. A crucial purpose of control units is convoy vehicles control, where the designed unit will be able to control of steering and speed actuators, where PWM signals were used for actuators control. These are based on a high level system commands. Control unit is able to send ultrasonic sonar and battery level data to the high level control unit. The communication between high and low level control systems provides an USART communication interface.

Modeling of DC motor in MATLAB/Simulink
Kunovský, Martin ; Kerlin,, Tomáš (referee) ; Hubík, Vladimír (advisor)
This bachelor’s thesis deals with the direct current motors, their properties and modelling. For modelling mathematic modul of direct current motor was created, which is linked to H-bridge and managed of PWM signal. After that general user environment GUI was created, which can run simulation after setting primary motor characteristic, and we can monitor it. This is executed in environment Matlab&simulink.

The Lighting system for auditorium
Novák, M.
This paper sums up the implementation of a cost effective lighting system, which cannot be realized directly using DMX512 due to its limited performance. The implementation consists of the network topology and the end device design. The overall design and results of a further analysis will be described.

Multilevel IGBT pulse-controlled rectifier
Bejvl, Martin ; Šimek, Petr ; Škramlík, Jiří ; Valouch, Viktor
A low voltage PWM rectifier 5 kVA based on IGBT multilevel converter has been developed. It is characterized by a low THD value of the grid current and can change the power factor. The modular arrangement of a grid filter makes it possible to test either L or LCL type of grid filters of different parameters. The PWM rectifier is equipped with the vector control of the grid current and superimposed feedback loop of dc voltage.
