Control of Magnetic Levitation Educational Model
Bednařík, Josef ; Brablc, Martin (referee) ; Matějásko, Michal (advisor)
The bachelor thesis deals with the modelling and control of the magnetic levitation CE 152 laboratory plant, which is specific in its nonlinearity and unstability. Firstly, all parts of the system are described by mathematical equations, which are the basis of the modelling of simulation model created in MATLAB/Simulink. Estimation of parameters is tackled by using the various of experiments and simulation’s model is validated with the real magnetic levitation system. Main body of the paper is focused on description and aplication of control on simulation’s and real model. It is realized by PID regulator, state regulator and feedforward regulator. In the last part of the thesis, the results are evaluated and compared among the all methods of control.

Special bearing types and its application
Polášek, Lukáš ; Vrbka, Martin (referee) ; Koutný, Daniel (advisor)
The goal of this bachelor’s thesis is to provide a search analysis of special bearing types. This work is focused especially to magnetic and air bearings, which are the most available and used special bearings. Both of these types are contactless, from which follows a big part their benefits. In this thesis there are introduced and explained the principles and design solutions of the most frequently used types of magnetic and air bearings. At the conclusion there are written up advantages and possible uses of these bearings.
