Digital controller for heating a press for molding plywood based on Simatic S7-1500, TIA Portal V12
Lesák, Michal ; Zemánek, Pavel (referee) ; Pásek, Jan (advisor)
This bachelor´s thesis deals with design of digital controller for heating press for molding plywood. The theoretical part is based on the scientific literature defines terms concerning hardware and software, which will use it for the controller design. The practical part, which will be made in the bachelor thesis, includes a controller design, which is performed by Totally Integrated Automation Portal from Siemens. Another, more work is engaged, the display and control with Basic panel of the second generation. The resulting controller will then be forwarded to the company Dieffenbacher as a function block, which can be put into practice.

Construction of educational model "Ball on Stick"
Coufal, Ondřej ; Formánek, Martin (referee) ; Dobossy, Barnabás (advisor)
The goal of this thesis was to create an educational model, which could be used as a demonstration of dynamic model and its regulation for future students of mechatronics. The construction was inspired by a similar construction but with much smaller dimensions where most of components were printed by a 3D printer. Afterwards there was created an electrical scheme and implemented on a printed circuit board. For the whole system was designed a caskade regulation, that makes sure the ball will reach the desired position, which is adjustable.

Implementation of PSD controller into microcontroler MCF52233
Lang, Stanislav ; Holek, Radovan (referee) ; Macho, Tomáš (advisor)
The goal of my bachelor thesis is the project and realization of a digital regulator, including the possibility of user’s settings. The first two chapters, which present a theory and a survey of the problem of digital regulation, offer an introduction as far as the used hardware (32-bit microcontroller M52233 from the company Freescale) is concerned. The main part of my thesis deals with the description of concrete implementation of regulation algorithms into the selected hardware as well as the communication with the regulation unit and the selection and basic configuration of the peripheral used.

Firmware for the Robotic Vehicle
Otava, Lukáš ; Sojka,, Michal (referee) ; Kučera, Pavel (advisor)
This thesis is focused on a firmware for robotic vehicle based on the ARM Cortex-M3 architecture that is running a real-time operating system (RTOS). Theoretical part describes available solutions of embedded RTOS and concrete HW implementation of the robotic vehicle. There is also comparison of the three selected RTOS with their measurements. Result of this thesis is base firmware compounded by a program modules that controls HW parts. There is also a sample PC and firmware application that extends base firmware. This sample application is able to communicate with robotic vehicle, control wheel motion and measure process data.

Implementation and analysis of control circuits in MATLAB/Simulink
Hanuš, Tomáš ; Houška, Pavel (referee) ; Singule, Vladislav (advisor)
The thesis is focused on comparing the characteristics of the most common types of controllers. This comparison is done in MATLAB / Simulink to model the DC motor. First, in the thesis, theoretical description of all structures controllers that are tested. This is specifically the PID controllers, PSD, PI-D, PS-D, S-PD, I-PD, PID filtering of derivative and PSD also with this filtration. Then there is the function given the DC motor and its mathematical description. In the last section of the theoretical part describes the different methods of setting regulators. In conclusion, this thesis compares the structure of individual regulators. There are the results. A comparison of their behavior with position control of DC motor.

Lab power supply 0-100 V / 0-100 mA
Hanzl, Ondřej ; Pazdera, Ivo (referee) ; Martiš, Jan (advisor)
The thesis deals with the design of a laboratory source of atypical parameters of the voltage range 0 – 100 V and current 0 – 100 mA, which will be used for testing LEDs, measuring the reverse voltage and characteristics of Zener diodes of unknown data. The power supply will operate in linear mode, where the output part make up a power unipolar transistor controlled by a controlled bipolar transistor. The control section controlling this output stage is a closed control loop with two PI controllers, a differential amplifier and a controlled limiter. In the control circuit, the controllers are arranged in a cascade structure, where the voltage regulator is superior to the current one. Power supply is provided by 2 transformers, one for the power part and the other for the control part. All designed and assembled components will be then placed in a box equipped with a digital measuring device with display.

Identification of DC motor parameters
Kabelka, Ondřej ; Veselý, Libor (referee) ; Pohl, Lukáš (advisor)
This bachelor´s thesis deals with identification of parameters of the DC motor. An identification program in LabVIEW with data processing in Matlab has been created. After the identification of electrical and mechanical parameters of the motor there are current regulators and velocity regulators designed and implemented in the LabVIEW enviroment as a verification of the correctness of the identification.

Continuous and discrete time attitude control of a vehicle
Najvarová, Lucie ; Nechvátal, Luděk (referee) ; Gennaro, Stefano Di (advisor)
Kontrola řízení vozidla se stala významným problémem v automatizačních aplikacích v automobilovém průmyslu. Ta se stala reálnou díky zavedení různých "by-wire" subsystémů, jako je např. "steer-by-wire," "break-by-wire," atd. Tyto subsystémy reprezentují elektronické ekvivalenty již existujících mechanických a hydraulických subsystémů. Především pak může být zavedeno číslicové řízení, určené na základě vzorkování dynamiky vozidla. Výhodou periodického snímání vstupních veličin je vyvarování se určitých poruch spojitého řízení.

Sanitary technical installations and gas pipeline in the apartment house
Polách, Petr ; Wierzbická, Helena (referee) ; Vaščáková, Alena (advisor)
The bachelor's thesis deals with the design of sanitary technical installations and a gas installations in an apartment house and with their connection to existing engineering networks. It also includes a design of a wastewater pumping facility to protect the underground rooms from the sewage flooding. It also includes a proposal for a light liquid separator, infiltration device and rainwater tank. The theoretical part is focused on gas main, fittings in gas distribution, gas pressure regulator and gas meters. Calculation and project part solves distribution of sewerage, water supply and gas pipeline in the specified object. It is a basement building with three aboveground floors and usable attic. On the ground floor of the apartment house there is a café.
