Affecting the efficiency of stimulation a strenght endurance through exercies on unstable surface
Jebavý, Radim ; Perič, Tomáš (advisor) ; Zháněl, Jiří (referee) ; Turek, Milan (referee)
Affecting the efficiency of stimulation a strenght endurance through exercies on unstable surface In our work we sought to verify the affecting the efficiency of a Strength programme of exercise on unstable surfaces for stimulation of strength endurance abilities, compared to a similar didactic programme conducted on stable surfaces, thus creating an alternative choice for coaches, teachers, and sports instructors. A major element of the didactic process is the quality of the strength training programme on stable and unstable surfaces. When evaluating the overall results of the tests before and after the experimental programme, we come to be of the opinion that the experimental programme manifested itself positively in effectiveness of stimulating strength abilities. The strength programme had an influence on increasing the persistence of strength in dynamic and static regimens. In the case of a strengthening programme on unstable surfaces there was a tendency towards greater growth in the number of repetitions as opposed to programme on a stable base at the beginning of the programme in the case of exercise in a dynamic regimen. Keywords: effectiveness, strength endurance preparation, unstable surfaces, stabilisation system.

Inteligent Controller of Active Magnetic Bearing
Turek, Milan ; Čech, Vladimír (referee) ; Ondrůšek, Čestmír (referee) ; Březina, Tomáš (advisor)
The PhD thesis describes control design of active magnetic bearing. Active magnetic bearing is nonlinear unstable system. This means it is not possible to use classic methods of control design for linear time invariant systems. Also methods of nonlinear control design are not universal and theirs application is not easy task. The thesis describes usage of simple nonlinear compensation which linearizes response of active magnetic bearing and allows usage of classic methods of control design for linear time invariant systems. It is shown that CARLA method can significantly improve parameters of designed controller. First part of thesis describes derivation of model of controlled active magnetic bearing and nonlinear compensation which linearizes response of controlled active magnetic bearing on input signal. Following part contains description of methods of state control design methods, selected methods of robust control design and most common methods of artificial intelligence used for control design and implementation. Next part describes hardware of used experimental device and its parameters. It also contains experimental derivation of model of electromagnetic force because the parameters are not available from manufacturer. Last part describes control design of active magnetic bearing. Several different approaches are described here. The approaches vary from completely experimental approach, through using Ziegler-Nichols method, state control design to methods for robust control design. During design is heavily used CARLA method which is very suitable for usage for online learning in real controller due its principle.
Realisation of the laboratory test instrument hardware for active magnetic bearing
Petrušek, Marek ; Turek, Milan (referee) ; Houška, Pavel (advisor)
The work is focused on the designing the active magnetic bearing and the construction of its fixing system. Hardware is designed to control the active magnetic bearing; it measures the rotation speed and does the following processing. The sensors produce the information about the magnetic bearing rotor location. The next part was dedicated to the development, which has been done in this field of interest. The used parts were mentioned with their characteristics and the function of power blocks was discussed. In the practical part, the realization of this magnetic bearing and the measurement of its location, power blocks and hardware behavior in the real design are described. The last part summarize all the work that was done.
