Commissioning and expansion of an unfinished three-axis manipulator
Metz, Lukáš ; Králík, Jan (referee) ; Appel, Martin (advisor)
The objective of this theses is the development of the technological components needed for the commissioning of an unfinished three axis manipulator. That includes designing the control electronics, which will be mounted on a custom printed circuit board, development of needed firmware and software, and also the derrivation and implementation of the motor control logic. The fully functional manipulator will then be equiped with a digital microscope and a functioning focusing mechanism, which will provide the device with a possible utilization in laboratory settings.

A traction drive for an electric bike with motor "Heinzmann"
Němec, Petr ; Huták, Petr (referee) ; Vorel, Pavel (advisor)
This work deals with a proposal and construction of a DC/DC converter for a control of a DC motor Heinzmann. The DC/DC converter will be used in an electric drive for a bicycle. The proposal of the DC/DC converter is designed for such engine power to avoid fully any human force to drive - pedaling. The work includes informations about the used motor, progress of proposal and dimensioning of the converter - power circuit and control electronics.

Onboard computer for electric scooter
Stříteský, Vladimír ; Burian, František (referee) ; Kříž, Vlastimil (advisor)
The aim of this thesis is clarify construction of onboard computer for electric scooter. There is description of components, from which the electric scooter is built. Within this thesis a computer simulation of accelerating scooter is created. Based on the simulation three possible ways of controlling the electric drive were proposed. Then thesis describe parts from witch control system is composed. Onboard computer and support circuits are described in more detail and explained their functions. Description of the created software is in the final part.

Sensorless velocity control and positions of d.c. low-power brush motor
Svoboda, Jan ; Hanák, Pavel (referee) ; Prajzner, Václav (advisor)
This bachelor's thesis focuses on sensorless control of low load brushed DC motor that is used in the actuators made by the Honeywell company. The first part provides an introduction into motor control and common used methods of speed and position sensing of brushed DC motor. Sensorless method of sensing described in this work is the detection of commutation pulses from the signal of motor current. These pulses are caused by brushes leaping over the commutator bars. Correct evaluation of commutation pulses can provide the information about velocity and position of the motor. This relatively new method of detection of commutation pulses is investigated and arising problems are demonstrated on measured samples of signal. Suitable methods of signal processing are then proposed. Infallibility of these signal processing methods is then proved on the set of signals measured under circumstances of supply voltage and abrasion. Then it is decided which signal processing method that sensorless control system can use is the best.

Injection System Build-in on Tractor Engine
Svršek, Michal ; Ramík, Pavel (referee) ; Dundálek, Radim (advisor)
The aim of this work is to design the installation of a new injection system to the existing tractor engines and construct new components necessary for proper function of the injection. In the following section is suggesting the location of other accessories for engine control. This is an injection system with a pressure reservoir "Common Rail" and all its components are created in modeling environment PTC Creo 2.0. Designed components are tested for strength and they are subjected to modal analysis.

Design of mechanical subsystem of tester for touch screen devices
Kopčil, Tomáš ; Venglář, Vojtěch (referee) ; Krejsa, Jiří (advisor)
Cílem této práce je navrhnout a sestavit systém pro automatizované nepřetržité testování dotykových displejů. Práce je zaměřena na mechanickou část, koncový efektor a motorizaci. Navržený koncový efektor je funkční na kapacitních dotykových displejích, přičemž snímá přítlačnou sílu působící na displej. Pohyb zařízení je zajištěn lineárními pohony s ozubeným řemenem, které jsou polohovány krokovými motory. Pro komunikaci s budiči motorů přes SPI protokol a pro samotné řízení motorů byla vytvořena knihovna zajišťující jejich lichoběžníkový rychlostní profil při pohybu. Sestavený testovací systém byl podroben 24 hodinovému spolehlivostnímu testu, během kterého byla ověřena jeho funkčnost, přesnost a opakovatelnost. Bylo také potvrzeno, že splňuje veškeré požadavky.

Autonomous Control System for Mobile Platform
Kříž, Vlastimil ; Burian, František (referee) ; Žalud, Luděk (advisor)
This work undertake the design of autonomous control system for mobile platform – slot car – for the Freescale Race Challenge 2009. The aim is to draw and implement control system, which will be able to drive the car trough the previously unknow path in the shortest time. In work is described factors that affect runing the car and draw optimal driving style. Then sensors for the car, type of motor control and control unit are chosen. The algorithms for maping the profile and for lap recognition are developed. Next the realization of the systém are descripted.

DC motor controller module
Duz, Aleksei ; Kadlec, Jaroslav (referee) ; Kuchta, Radek (advisor)
This thesis focuses on the design and creation of control unit for DC motors drives. A principle on which the DC motor is based, a method of its control and a possibility to obtain current information about the position are briefly described in this work. After that, the different types of buses for communication with a superior system and justification of the chosen one, are presented. In the next section, there is a special emphasis on creation of the suitable driver model and a design of the elecrical schematic and PCB. The end of the thesis contains a description of commission a PCB and testing the main functions.
