Stepper motor driver equipped with industrial communication
Nepivoda, Tomáš ; Baštán, Ondřej (referee) ; Arm, Jakub (advisor)
The main goal of this bachelor thesis is to design and realize driver for stepper motor, which could be controlled by supervising system using modern industrial communication network. The basis od this thesis is theoretical study on the subject of stepper motor drivers and industrial communication in the field of embedded systems. This theoretical study is then used for selecting the proper communication network and creating concept od the stepper motor. Thesis further describes design procedure and realization of hardware components and subsequent implementation of frimware. Last part of the thesis is dedicated to the creation of simple master device, which would be used for driver testing.

Camera slider control
Rajnoch, David ; Götthans, Tomáš (referee) ; Mego, Roman (advisor)
This bachelor thesis describes design and implementation of stepper motor digital controller that manages camera slide movement. The main elements are microcontroller ATmega16 and stepper motor driver TOSHIBA TB6560. Controller allows a time-lapse mode and continuous linear movement including smooth start and stop. Human interaction is based on joystick input and text display connected via HD44780 interface. The theoretical part describes stepper motors and their control modes. The practical part deals with design of electronic circuit and test of functionality.

HMI automatic tester
Lang, Stanislav ; Žalud, Luděk (referee) ; Macho, Tomáš (advisor)
This thesis is dedicated to the automation of tests of the thermostats developed by the company Honeywell. The first chapter presents a problem of self-testing of thermostats, followed by a discussion of possible approaches to solutions. Attention is paid to testing the functionality of the HMI of thermostats, especially to the part of the system, that deals with activation of touchscteen, but no other part of the problem are omitted in the text. Discussions of the problematic passes into the design and implementation of specific design solutions. The selected design of 3D-router, which moves in three orthogonal coordinates and resembles to a coordinate drill for example. First, it describes the basic concepts of mechanic and electronic part of equipment, and subsequently is designed and implemented control electronics for mechanical activator HMI. Each of the electronics components are described in detail and values of parts are based on the calculation with the exception of finished parts. The proposal of the electronics follows the possibility of maximization of universality module for applications in similar applications. The functionality of the electronics is controlled by a microprocessor with a custom program that is described in the work. Source code of some the programs is not available because it is know-how of the company. Next part of the thesis deals with optimization of the moving of axes, optimization is done empirically by measuring. An important issue is compliance with the accuracy required position, also part of the work is devoted to the issue of calibration position. Finally is solved the continuity on the superior system. It is designed and implemented the upper layer of the communication protocol used in the company. Work is the solution of specific corporate award thesis. Although it is a very specific role of the works are generally applicable for other applications. In particular, the proposed electronic represents relatively universal controller for stepper motor control.

Design of special antenna rotator
Půhoný, Jan ; Ježek, Michal (referee) ; Kovář, Jan (advisor)
This master's thesis deals with design electronics for an antenna rotator in two axis. There are designed and implemented drivers for two stepper motors. Was also designed and implemented control panel that allows manual control the rotator and remote control by PC via USB. At the same time created software for control panel and PC application for easy operation.

Stepper motor feedback control
Mach, Martin ; Buchta, Luděk (referee) ; Blaha, Petr (advisor)
Goal of this thesis is to familiarize your-self with NCV70514 stepper motor driver by ON semiconductor, the function of bipolar stepper motor, hardware and software equipment developed for driving of NCV70514 and to explore possible algorithms for current and velocity adjustment to load by the means of back EMF. A simulink model was created for verification of said algorithms. The output is theoretical analysis and outputs of simulation. Futher more is to implement such algorithms in said microcontroler a then create graphic user interface running under Windows OS.
