The manipulator SMC MAP 205 control
Ďuriš, Martin ; Němec, Zdeněk (referee) ; Marada, Tomáš (advisor)
The thesis deal with a model of electronically controlled assembly minicell MAP-205 based on pneumatic drives and its debugging. Assembly minicell simulates assembling and disassembling of simple four item assembly. Minicell is controlled by Phoenix Contact ILC 150ETH programmable logic controller. The minicell control program is composed of several subroutines/subprograms providing various functionalities to assembly minicell. There is integrated HMI created in Control Web application too. It allows to display actual status of each component and to control each drive in manual mode. Communication between HMI based on PC and PLC controller is supported by Bluetooth module and OPC server.

Description Methods for Electrical Systems and Their Solving
Křižka, Jakub ; Němec, Zdeněk (referee) ; Šeda, Miloš (advisor)
The objective of bachelor thesis is a searching description of methods, which are usually used for calculation of circuit variable values in electric circuits. At the beginning is thesis concerning with description of individual components (power supplies, electronic components) used in electric circuits, then also with analysis of rules, which are the fundamental for a calculation of values in electronic circuit – Ohm’s rule and Kirchhoff’s rules. Indivisible part of thesis is also summary of special methods, such as method of loop currents (mesh analysis), method of nodal voltage (nodal analysis) etc. and their demonstration on examples of electric circuits. The structure of thesis is coursebook and gives successive summary of information in area calculations of electric circuits.

PLC Drive Control by means of CAN Bus
Polach, Tomáš ; Němec, Zdeněk (referee) ; Matoušek, Radomil (advisor)
The theme and goal of this diploma is a draft and a method of application of a drive algorithm of an omni directional robot. The robot is driven with the aid of a PCL from the X20 series, produced by Bernecker&Rainer. The propulsion is provided using 3 integrated regulating driving mechanisms, IclA D065 produced by SIG Positec, which communicate via the CAN bus. Furthermore, the robot uses sensors to read the positioning of its chassis and undercarriage in order to identify the traction quality of the surface of the terrain below and subsequently reduce skidding. This sensor uses the RS 232 bus to communicate with the PLC. Thanks to all the above-mentioned and characteristics of power supply, the result achieved is a totally autonomous machine.

Simulation of long heat pipeline operation control
Seriš, Richard ; Nykodým, Libor (referee) ; Němec, Zdeněk (advisor)
The objective of this diploma thesis is to design a model of long heat pipeline operation control using Matlab software. The model should simply correspond to real heat pipeline system Melnik – Praha. After this, simulate operation control of sets of pumps. The role is to simulate usual and critical modes of operations. After evaluation of results, optimize the conditions for operation control of this system.

Economical housing
Marek, Vojtěch ; Němec, Zdeněk (referee) ; Dosoudilová, Monika (advisor)
The bachelor's thesis is focused on the creation of an economical housing system using a compact programmable controller Siemens LOGO!. The work includes a description of logic control and approach to the problem of programmable logic controllers. The practical part deals with a simplified design of a housing unit using control programs and the actual implementation of the house model. The software LOGO! Soft Comfort was used for the actual implementation of the program. Autodesk Inventor software was used for creating of the parts needed for the model. The work is supplemented by photographs of the model itself and control programs.

Automatic process control of aftercooling in brickkiln
Cacek, Jan ; Ošmera, Pavel (referee) ; Němec, Zdeněk (advisor)
The thesis deals with the design of the multivariable automatic control system of aftercooling process in the brick industry tunnel kiln. Theoretical part submits the facilities of controlled systems identification and the design methods of uni and multi variable systems. In the practical section is cleared up the principal of the aftercooling process and its identification based on the measured data. The output of the thesis is the design and the analysis of multivariable system with the conservation of the control circuit autonomy.

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.

Sacristian bell operation control by programmable logic controller
Křížek, Ladislav ; Marada, Tomáš (referee) ; Němec, Zdeněk (advisor)
The bell is described, its parts and constructive suppositions for the right function in this work, sacristian bell operation control with hand-working and with the rotating electromotor. Programmable logic controller machine SIEMENS Simatic S7-200 CPU 221 is also described, which is the part of ringing machine in Bukovinka’s church. This ringing machine and especially the mode of both bells have specific defect. According to owner´s wishes and instructions were two variants prepared for this ringing machine to improve the working of couple bells. One of these variants was tested and just tuned at the ringing machine. This one variant follows the owner´s wish, works in Bukovinka´s church till now.
