Commissioning of a laboratory model of modular converter in full Delta connection
Janovec, Jiří ; Kokeš, Petr ; Semerád, Radko
A laboratory model of MMC (Modular Multilevel Converter) was created and put into operation. The converter consists of series-connected FHB (Full H-bridge) cells and other necessary devices (for measurement, synchronization and pre-charging). The MMC was tested in topology of full Delta connection with 5 cells in each of 3 branches. The MMC was loaded for symmetrization of 1-phase 3.4kW resistive load (i.e. the branch current approached 5Amp rms). The power cells were completed with Slave units EPX and then controlled using TwinCat development system and EtherCat industrial data network. With the converter, control algorithms for symmetrization and compensation of 1-phase load for 3-phase power grid were tested.

Digital commissioning of robotic machine tool operator
Tecl, Michal ; Szabari, Mikuláš (referee) ; Vetiška, Jan (advisor)
The diploma thesis deals with the issue of digital commissioning of robotic operation of CNC machine tools. In the research part, individual types of industrial robots are analysed, including their advantages and disadvantages for the given application. Furthermore, several software used for digital commissioning are described and the possibilities of communication between machine tools and robots are described. In the practical part, a model task of operating two CNC machines is created. A suitable robot, robot tools, part magazines are selected, and a 3D model of the entire workplace is processed. In the final part, both a program for the robot and a program for the PLC controlling the entire workplace will be created.

Design and implementation of the control for the robotic cell
Mbontar, Patrik ; Pochylý, Aleš (referee) ; Kubela, Tomáš (advisor)
This master´s thesis thesis deals with the design of software for the control of a robotic cell, which consists of two KUKA robots and a belt conveyor. The robots will perform robotic operations similar to those in real industrial practice. At the beginning of the work will be the state of current knowledge. A key part will be the design of software for robotic cell control in the TwinCAT environment from Beckhoff. The robots and the conveyor will be controlled by a superior PLC, which will be commanded from the designed software using the HMI. The goal is to successfully implement the proposed software for robotic cell control and monitoring using a unique visualization, which will be designed specifically for the robotic cell and its associated manipulation operations.

The modernization of control system of milling machine FNG
Holas, Jiří ; Vetiška, Jan (referee) ; Bradáč, František (advisor)
This thesis deals with a proposal modernisation of control and electroinstalation of the milling machine FNG 32. The thesis is divided into several sections: The first section is dedicated to the research of the milling machine and the description of its current condition. The second section deals with possible options of retrofitting and with the components.The third section includes the technical and economical evaluation and the selection of the solution. In the next section, the selected components are described and an electronic documentation of the machine has been created in EPLAN. In the last section, a proposal of control of the milling machine has been created with the help of the TwinCAT development environment provided by Beckhoff company.

Software Implementation of Lowest Level Control for FB-MMC Converter
Kokeš, Petr
For FB-MMC converter (Full Bridge Cell, Modular Multilevel Converter), the software implementation of SA-PWM modulation (Sampled Average PWM) and SORT-BAL sorting type balancing of cell voltages have been designed. The report deals with the specifics of realizing control methods using the Beckhoff TwinCAT 3 system. The control structure was divided into explicitly defined function blocks for the Master controller as well as for the distributed EPX Slave units. Data transfer timing between the Master and the Slave units has been designed and the synchronization of EtherCAT link communication has been tested in practice. \n

The modernization of CNC system of milling machine EMCO
Kučera, Vítězslav ; Vetiška, Jan (referee) ; Bradáč, František (advisor)
This master´s thesis deals with the modernization of the EMCO milling machine control system. The theoretical part is focused on the basic description of CNC machine and current state of EMCO milling machine control system. The main point of this thesis is new control system design for given milling machine, when the proposed variants are described and compared according to construction and price. The one variant is selected that best suits the specified parameters. Also, in the TwinCAT development interface from Beckhoff the new control system is created and described in the end of this work.

Design for testing device used to measure air leakage from linear pneumatic actuator
Kurillová, Katarína ; Tůma, Zdeněk (referee) ; Vetiška, Jan (advisor)
This thesis is focused on detecting air leakage in serial production of pneumatic linear actuators. Testing for air leakage is an important part of the production process in which the manufacturer ensures that the product satisfies quality requirements and works correctly. The thesis was created in collaboration with the Czech manufacturing plant of SMC Industrial Automation CZ s.r.o., which produces pneumatic actuators. Goal of the design part of the thesis is to select the most effective method for testing and finding universal principle for testing in specified conditions. The principle is then applied to design a testing device for the CQ2 cylinders. The testing device consists of three parts - pneumatic circuit, control circuit and electric circuit. Thesis conclusion contains comparison of the newly designed testing device with the device currently in use.
