Universal drive unit
Sehnálek, Lubomír ; Frýza, Tomáš (referee) ; Fedra, Zbyněk (advisor)
This document deal with design of universal driving unit. For the final solution is required driving unit which will be controled with help of sensory unit placed on the chassis of driving unit. In theoretical part of this labour are examined possibilities of a power, electric motor operation by PWM, kind of chassis and odometry which could be taken into account. From this section is finally chosen concrete configuration which is then described in chapter concerned oneself with driving unit design. Construction of equipment is shown in next chapter where final configuration of equipment is described.

Microprocessor Controlled Measurement and Control Temperature
Vožda, Michal ; Čížek, Martin (referee) ; Sekora, Jiří (advisor)
The aim of the project is a design of the temperature controler based on microprocessor. There are described the most widely used sensors for the temperature measuring and their involvement in the electric circuit. The temperature controler is based on the Peltier’s thermoelectric battery. Project desribes power control of this thermoelectric battery and also a design of the entire system and a description of the blocks takes a part.

Positioner for Solar Panel with Power Efficiency Optimizing
Kreysa, Karel ; Punčochář, Josef (referee) ; Šebesta, Jiří (advisor)
This thesis is focused on design and prototyping of solar panel position control system for an obtaining of the maxima renewable energy from sun. In this thesis, various ways of solar panel positioning are considered and analyzed. Consequently, a construction arrangement of the positioner is presented. It is mechanically adapted to obtain the maximum efficiency in typical environment corresponding with the Central European geographical latitude. Different methods of sun monitoring are considered and analyzed. On the basis of this analysis, a proper prototype of sun monitor for exact positioning with disturbance filtering has been constructed. Following part of work is devoted to stable, fully automated, control subsystem for reliable functionality of solar system. A suitable microprocessor with a robust firmware has been implemented to this control unit. Finally, system parameters measurement and closing analysis of gained renewable energy and backflow computation is presented in the end of this diploma thesis.

Digital secondary clock
Hortvík, Martin ; Mašek, Petr (referee) ; Marada, Tomáš (advisor)
The aim of this thesis is to design and implement control electronics for digital secondary clocks. The first part is focused on familiarization with the issue of the use of secondary clocks. Subsequently, the work deals with the design of electronics for generating minute pulses. The first part of the proposal is to ensure the correct voltage size and polarity of pulse. The exact timing pulses are provided by a pair of control circuits, Atmega8 microcontroller and RTC. The last part describes the procedure of realization of electronics by making schema, design and manufacture PCB, circuit revive and the implementation of the module into case.

Manipulator control via microcontroller
Šíl, Petr ; Liška, Radovan (referee) ; Zuth, Daniel (advisor)
This bachelor thesis is dedicated to the control of the manipulator by microcontroller. It is a scale model of the manipulator, which will demonstrate the functions of a similar manipulator in the real time practice. The design of the manipulator consists of two parts, the mechanical part and driving part. In each section were chosen suitable parts to fulfil requirements of desired functions. The functionality, simplicity of manufacturing of all sections, the price and simplicity of control were the main criteria during the design of the manipulator. The system utilised ATmega 128 and development environment AVR Studio 4 to control and test microcontroller ATmega128.

Multifunction data acquisition, measurement and control device
Trávníček, Ivo ; Vlachý, David (referee) ; Grepl, Robert (advisor)
The thesis deals with and tests the Multifunction data acquisition, measurement and control device. The unit is based on the microcontroller ATmega, which was programmed in the language C. The unit contains functions for the measurement of physical quantify, filtering record, regulation of the dynamic systems and communication with PC. Configuration of the unit is real-time in special software created in the language Matlab or by a terminal. The purpose of the unit is controlling a DC motor by the PID regulator, long-term measurement of temperature or measurement of acceleration by an accelerometer.

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.
