Nonlinear models of DC machines
Král, Michal ; Mišinger, Lukáš (referee) ; Mach, Martin (advisor)
This bachelor thesis deals with modeling and simulation of DC motors. Four models of DC motors were created, according to four types of excitation ( derivative, serial, compound and separated). These models were designed in simulation program MATLAB & Simulink. Models were adjusted in order to respect magnetic non-linearity. Parameters for simulations were measured on real DC machine and the simulations were executed. This theses focuses on examination of temporary effects and comparing with real measured developments.

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.

Parameters identification of DC machine coupled model
Kraml, Aleš ; Huzlík, Rostislav (referee) ; Vlach, Radek (advisor)
This thesis deals with design and implementation of experiments leading to identification of parameters of a DC machine, creation of its model with coupled electrical, mechanical and thermal part. The first part describes various methods of modeling thermal resistance between body and ambient and the methods are compared. Furthermore, methods of identifying coefficient of damping and identification of moment of inertia are described. Second part of the thesis describes preparation and identification of resistance of the winding, inductance, heat capacities of rotor and housing and parameter c and measurement of damping coefficients. In the next part, the creation of a Simulink model of the DC machine is described. Furthermore, this thesis describes the algorithm for identification of parameters of an existing machine and the possibilities of using the model and identification in the development of a new machine. The next part assesses using the algorithm of identification and model as a basis for the creation of a virtual twin.
