Control of asynchronous motor
Semerád, Jiří ; Pazdera, Ivo (referee) ; Běloušek, Josef (advisor)
The thesis is focused on asynchronous motors. The first part deals with construction, principles of function and speed-torque characteristics of the motors. Furthermore, a mathematical model of an asynchronous motor in Matlab-Simulink program is created in order to make a possibility to test any type of motor and check all parameters, which is more economical than testing real objects. The second part of the work contains an overall summary of asynchronous motor control methods.

Control algorithms for BLDC motor for low speeds
Kozáček, Peter ; Pohl, Lukáš (referee) ; Veselý, Libor (advisor)
The diploma work concerns on an issue of data collection of speed and electrical angle based on informations from Hall sensor with the necessary resolution for control of BLDC motor. Specifically, concenred on a section with low speed. Most of moors use Hall sensor for detecting speed and position of the rotor. At low speed section, becomes the situation when we can not determine the position of the rotor with (the) required (sufficient) resolution, this situation creates a „wince“ in the control (ripple torque). The task is to design and evaluate the possibilities of the algorithm for control and acquisition speed and rotor position with the required accuracy.

Algorithms for the Control of the Induction Motor
Hundák, Vladimír ; Běloušek, Radim (referee) ; Patočka, Miroslav (advisor)
Hlavným cieľom tejto práce je vytvorenie simulácií rôznych algoritmov riadenia asynchrónneho motora a vzájomné porovnanie ich vlastností. Zaoberá sa taktiež možnosťami konfigurácie náhradného zapojenia na T-článok, -článok a -článok. Obsahuje jednak teoretický rozbor, a taktiež aj simulácie jednotlivých spôsobov riadenia spolu s podrobným návodom na ich realizáciu. Celkovo budú vykonané 3 simulácie – simulácia vektorového riadenia s orientáciou na rotorový tok, vektorového riadenia s orientáciou na statorový tok a simulácia takzvaného prirodzeného riadenia. Ide o úplne nový typ riadenia, ktorého autorom je vedúci tejto diplomovej práce. Jeho simulácia bola vôbec prvým pokusom o funkčnú realizáciu tohto typu riadenia.

Control of the Electromechanical System with a Linear Motor
Judinyová, Katarína ; Blaha, Petr (referee) ; Václavek, Pavel (advisor)
The submitted Master’s thesis deals with the general principle of the electric drives’ functioning and with the construction of a synchronous electric motor. A comparison of a linear drive and a rotary drive with rack and pinion system is provided, as well as an overview of common type linear drives. A mathematical model of a rotary synchronous motor, the Clark’s and Park’s transformation and the principle of vector control is explained. A method of the linear parameters’ conversion to the rotary equivalents is demonstrated. A block diagram to motor control is designed. The control quality is tested by various criteria. Lastly, there is a simulation provided on how the changes of motor’s parameters affect the control quality.
