Design of control unit for an autonomous vehicle
Vobruba, Martin ; Formánek, Martin (referee) ; Adámek, Roman (advisor)
The topic of this bachelor thesis is designing control unit for an autonomous vehicle. The new ECU replaces the old one which was without access to the source code, so its functionality couldn’t be modified. The purpose of the ECU is to receive a message from the control computer, process it, control the actuators according to the orders and inform the computer about their current state. The first part of the thesis is research of the vehicle kinematics and CAN bus. The practical part focuses on the analysis of the previous ECU which is crucial to its replacement. It is followed by the firmware and hardware design. The last practical part of the thesis is the testing of the new ECU’s functionality.

Power supply module for servo-drive
Kudláček, Pavel ; Procházka, Petr (referee) ; Červinka, Dalibor (advisor)
The aim of the diploma thesis is to theoretically design and to put the mains power supply module for two-axis servo amplifier TZG 560 with the total power 28kW for the company TG Drives into practice. The analytical design of the power part with the braking circuit, the calculation of power components’ heat balance, EMI filter design and realization of measuring, controlling and indication circuits are described in the thesis. In addition, the mechanical device construction, structure of the controlling program and the results obtained in the verification process of the module functionality are presented.

Control of special purpose machine tool
Plocek, Jaroslav ; Holub, Michal (referee) ; Houška, Pavel (advisor)
The master thesis treats the design of control system of special purpose machine tool. The first part analyzes and compares two possible variants of control system which use either a CNC control system Sinumerik or motion control system Simotion. Only the variant with the Simotion control system is subsequently examined in detail: its hardware configuration, the selection of components and partly also the software solution. The thesis further deals with the safety of the realized control system and of the whole machine. There are described general safety requirements of machinery based on harmonized European standards and their specific application in the design of safety functions and the safety circuits of solved machine tool.

Position control of cross-table dedicated manufacturing machine
Plocek, Jaroslav ; Vetiška, Jan (referee) ; Houška, Pavel (advisor)
The bachelor thesis treats the drive solution of the two axis cross-table of a single-purpose manufacturing machine. The first chapter analyzes the concept of drives and compares different variants using either a direct linear drive or a ball screw with a rotary servo drive. The thesis further deals with sizing the motor and the power unit assembly and the description of the whole measuring system. The structure of cascading position controller, its description and the calculation of current and speed control loops is covered in the next part. The last section discusses practical settings of all control parameters.

Design of linear ball screw actuator for higher axial load
Turek, Lukáš ; Klapka, Milan (referee) ; Koutný, Daniel (advisor)
This bachelor thesis solves the construction of a servomotor with a moving screw for higher axial loads. The aim was to design a servo actuator for an axial load of 25 kN, which can be clamped from both sides. The partial goals were to develop an overview of electro-mechanical servo actuators, to analyze the force ratios, load capacity and service life of the current actuator solution. Further process the calculation and design of the actuator, including drawing documentation of selected components for higher axial loads.

Presses with direct drive of current production
Bajdich, Matej ; Dokoupil, Vladimír (referee) ; Omes, Jiří (advisor)
The aim of this work is to analyze to the issues of mechanical presses with direct drive, their comparison with mechanical presses driven with indirect drive and introduction of presses with direct of current production on the market. In the first part of bechalor's thesis, it looks at the basic information about mechanical presses, the division of mechanical presses and describes the current state of selected mechanical presses on the market. In the second part, the works deals with the calculation and design of direct and indirect drive according to given parameters. 3D model of drive is created from the design of direct drive. To the part of the 3D model, the brackets for attaching the servomotor to the press body, production drawnings are attached. The last part of the thesis deals with the comparison of results from the second part of the thesis, the evaluation of the diferences between the direct and indirect drive of the mechanical presses resulting from the first part of thesis. Last but not least the author's view when comparing the drives and the idea of the next development of the direct drive technology in mechanical presses.

Control of a servo-drive for a 3-axial rotary table
Trizna, Lukáš ; Klusáček, Ondřej (referee) ; Macho, Tomáš (advisor)
The aim of this master’s thesis Control of one servo-drive of three-axis rotary table is to develop a real-time motion control solution for the commercially available servo drives on the base of perspective solution available in the industry and the implementation of the chosen solution. The project includes the description of the current solution for the rotary table control, the description of suitable on the market available controllers, the rotary table control design for two selected controllers, the designed model on the base of identificated parameters of DC engine, the design of current, velocity and position regulators for the servo drive control, the servo drive control implementation by two selected controllers ESCON and EPOS2, the servo drive control function verification and the evaluation of achieved results.
