Mathematical model of synchronous motor width permanent magnet
Fajkus, Petr ; Klíma, Bohumil (referee) ; Huták, Petr (advisor)
The work is focused on the design of synchronous motor control with field weakening possibility. At present synchronous motors used in many applications. Often is used synchronous motor with permanent magnets. This type of motor may have different transverse and axial inductance. In most cases it is desirable to design the engine using a computer model. Therefore the synchronous motor described mathematically in order to create the model of motor. At work is also crated model of synchronous motor control. The control is designed for the highest possible speed range. Therefore, the motor control is consist of two parts. Speed is controlled by voltage in the first part. In the second part speed is controlled by field weakening. Everything is created and simulated in a computer program MATLAB-SIMULINK.

Control of dividing attachment
Španěl, Petr ; Procházka, Petr (referee) ; Huták, Petr (advisor)
Automatic cutting machine can cut wires and cables to user-defined length at a specified number of pieces. These equipments are usually custom-made for needs of the requested application and they are not very spread out tools on the Czech market. This described device is specified for efficiency-rise in the production of heat-resistant cables. These prepared cables are used for internal connection of the resistors.

Control of salient PM machine using d-q frame machine model and Matlab Simulink
Dušek, Jiří ; Huták, Petr (referee) ; Ondrůšek, Čestmír (advisor)
Tato práce se zabývá synchronním motorem s permanentními magnety na rotoru (PMSM), jeho modelováním a návrhu regulační struktury. V práci jsou uvedeny způsoby a výhody použití permanentních magnetů v elektrických motorech. Dále se práce zabývá transformací třífázové soustavy do dq0. Pomocí Parkovy transformace jsou v práci odvozeny rovnice stroje v dq0 souřadnicovém systému a vytvořeny náhradní schémata stroje v dq osách. Rovnice i schémata zahrnují jak ztráty v mědi, tak ztráty v železe. Náhradní schémata jsou popsány elektrickými a mechanickými rovnicemi a následně překresleny do grafické podoby v programu Matlab Simulink. Vytvořeny jsou dva modely PMSM, jeden s uvažováním ztrát v železe a druhý bez těchto ztrát. Pro oba dva modely je zde popsán postup návrhu regulátorů proudu a otáček. Pro model, u kterého jsou uvažovány ztráty v železe je navíc použito více druhů řídicích strategií a tyto strategie jsou mezi sebou navzájem porovnány.

DSP56800 microprocessor line usage for asynchronous motor control
Kukuczka, Adam ; Huták, Petr (referee) ; Klíma, Bohumil (advisor)
Tato diplomová práce pojednává o možnostech simulace a modelování elektrických pohonů na základě Bondových grafů. Je zde uvedena základní teorie k problematice. V práci jsou představeny modely stejnosměrného a synchronního stroje sestavené touto technikou. Dále je zde seznámení s Freeware knihovnou Bondových grafů BG V2.1 k programu MATLABSimulink. Za pomocí této knihovny byly sestaveny oba modely strojů. V poslední kapitole je uvedeno srovnání modelování na základě teorie Bondových grafů s modelováním v blokových diagramech.

A traction drive for an electric bike with motor "Heinzmann"
Němec, Petr ; Huták, Petr (referee) ; Vorel, Pavel (advisor)
This work deals with a proposal and construction of a DC/DC converter for a control of a DC motor Heinzmann. The DC/DC converter will be used in an electric drive for a bicycle. The proposal of the DC/DC converter is designed for such engine power to avoid fully any human force to drive - pedaling. The work includes informations about the used motor, progress of proposal and dimensioning of the converter - power circuit and control electronics.
