EDU-mod models
Janů, Ondřej ; Voldán, Jiří (referee) ; Marada, Tomáš (advisor)
This bachelor´s thesis deals with the design of EDU-mod model. EDU-mod models are used for teaching control systems. The thesis deals with the design of control circuit with microcontroller, programming this circuit and with the design of demonstration tasks. Model is controlled by Atmel ATmega128. Microcontroller was programmed by Biprog programmer, which was made for the purpose of this work. Designed tasks were programmed in STL programming language in STEP7 Micro/Win development environment. Functionality was verified by controlling by PLC SIEMENS Simatic S7-224XP.

EDU-mod models
Zubál, Vladimír ; Voldán, Jiří (referee) ; Marada, Tomáš (advisor)
This bachelor’s thesis deals with the EDU-mod models which are parts of equipment in the laboratory of programmable controllers at the institude of automation and Computer Science of the Faculuty Of Mechanical Engineering at Brno University of Technology. The aim of this study is to get aquainted with EDU-mod models serving as teaching aid.Then design and implement own models.Furthermore,design examples and verify the features of models by PLC .

Microprocessor control unit design
Voldán, Jiří ; Marada, Tomáš (referee) ; Věchet, Stanislav (advisor)
This thesis deals with a design and implementation of a microprocessing control unit which can be used e.g. for controlling a hydraulic loading crane. This multi-purpose control device contains commonly available computer peripheral components such as a serial line, a USB connection or Bluetooth. When specific sensors are added to this device it can be used for measurements as well as for adjustments. This device also enables to store measured data on an SD/MMC card.

Dynamic characteristics drive with frequency inverter
Loveček, Vladimír ; Marada, Tomáš (referee) ; Voldán, Jiří (advisor)
This bachelor thesis deals with a proposal of measurement equipment and software equipment for evaluation of the dynamic characteristics of the drive controlled by frequency inverter, and with subsequent measurement and evaluation. Torque measurements are made using the incremental encoder and evaluated on the basis of mechanical characteristics by development environment MATLAB.

Servomechanical movement control of photovoltaic panel
Uher, Ondřej ; Voldán, Jiří (referee) ; Němec, Zdeněk (advisor)
Thesis deals with the introduction to the production of electricity using photovoltaic panels and the relative position between panels and the Sun. The project aim was to design equipment to ensure the vertical position of the solar panels towards the Sun during the day so as to achieve maximum energy gain from sunlight. Pointing mechanism will be governed by the date and time.

Automatic control for factory building heating
Prudek, Miroslav ; Voldán, Jiří (referee) ; Němec, Zdeněk (advisor)
The graduation thesis is focused on the automatic operating of heating of the production hall of První brněnská strojírnaVelká Bíteš, a.s. The thesis consists of an analysis of present state of the heating technology and solution of the general conception of the automatic operating of the heating. Integrated part of the conception is heat-up of the supply water and drain off of the condensation water from the air heating units. Outcome of this graduation thesis is a design of the algorithm for operating of the regulated system. Remote supervision and control of the regulated system shall be ensured by the visualization setting, which shall be implemented into the station of dispatching centre. The accuracy of the design of the part of regulated system shall be validated as a design of PID regulator with the use of “Matlab” program and it´s module “Simulink”. To set up parameters of the PID regulator, “Ziegler-Nichols” method shall be applied. The objective pay-off period of investments for regulation controlling system is figured out as a part of this thesis as well.

The influence of physical activity on postural function disorders in school children
Voldán, Jiří ; Vařeková, Jitka (advisor) ; Prajerová, Květa (referee)
Title: The influence of physical activity on postural function disorders in school children Objectives: The objective of this thesis is to evaluate the state of postural function of pupils of 4th, 7th and 9th grades, and to measure their physical activity and subsequent evaluation of the impact of physical activity on the incidence of functional postural disorders in these children. Methods: The thesis used methods of observation and questionnaires. Evaluation of the state of postural function was held by observation using test evaluation of posture according to Jaroš and Lomíček. The rate of children's physical activity was detected using a questionnaire. Results: It was found that pupils who are not engaged in any organized physical activity is a greater incidence of functional postural disorders and overall condition of postural function is worse than that of students who play sports. Keywords: physical activity, postural functions, school children, evaluation
