Simulation of electric machines
Klíma, Jiří ; Mišinger, Lukáš (referee) ; Mach, Martin (advisor)
This thesis deals with modeling and simulations of DC and AC machines. They were created by four mathematical models. Three models of DC motors with different type of excitation (compound, serial, derivative) and one model for asynchronous motor. All models were implemented in MATLAB & Simulink. After measuring and setting the basic parameters of the machines, simulations were running. Simulation results are then compared with measured waveforms.

Vehicle Navigation Systems
Mišinger, Lukáš ; Janda, Marcel (referee) ; Hájek, Vítězslav (advisor)
This bachelor thesis consider contemporary navigation systems or systems that will be at work very soon. This work includes main parting of satellite navigation systems and their functions and charakteristics, board units of navigation systems and their usage in vehicles. Next part is about another usage in transportation jointed sevices. Last part is about suggestion for laboratory practise with specialization on navigation systems for lessons of subject BAEB (Vehicle elektrotechnics).

Application of the Simatic control system for the packaging machine control
Urbánek, Tomáš ; Mišinger, Lukáš (referee) ; Knobloch, Jan (advisor)
Masters thesis deals with the SIMATIC, which is the process control system from Siemens. Simatic belongs to the group of so-called programmable logic controllers (English Programmable Logic Controller). It is a microcomputer that processes the instructions in real time. I have designed a control algorithm and HMI visualization in my Masterś thesis. Moreover,my attention is focused on PLC S7 - 300. The S7-313C is used for implementations. The proposed solution has been tested and operated in real conditions

Improving the operating characteristics of sliding contact
Mišinger, Lukáš ; Hájek, Vítězslav (referee) ; Veselka, František (advisor)
This master's thesis is focused on comparison of various conception of slide contacts. Studies of this theme are based on laboratory models and consequential experiments and measurements to the application of innovated slide contacts. The innovation is based on application Teflon on the slide contact's components. In this project there are presented results from measurements with application of innovated brushes „sT“, brush holders with „sT“ and new conception of slide contact with auxiliary teflon brush on DC machine. Next part is about innovation of trolley-bus traction collector, which was used on trolley-bus and results of its laboratory experiments. The last part presents results of long term experiments with "sT" technology, which was applicated in a few variants of industrial usage.
