Coupled model of synchronous machine
Šmída, Michal ; Kraml, Aleš (referee) ; Vlach, Radek (advisor)
This thesis focuses on creating a coupled model of a synchronous motor using Matlab. To make a coupled model, it is necessary to correctly determine the surrogate schematics that represent the physical domains-electrical, mechanical and thermal. The combination of these parts can be called a coupled model, which captures their interdependence. The main goal of the work is to make the output of the model as close as possible to the real machine.

Coupled model of DC machine
Komorous, Jan ; Kraml, Aleš (referee) ; Vlach, Radek (advisor)
This thesis focuses on the creation of a DC motor model with an emphasis on the interconnection of individual domains and subsequent comparison with real behavior. In the first part, the model is created using equivalent substitute diagrams for the electrical, mechanical, and thermal parts. In the second part, the implementation is carried out using MathWorks software, along with the creation of a missing block for heat transfer by natural convection. The resulting behaviors are compared with a real DC motor.

Properties examination of complete matrix and its cofactors for symbolic calculations
Kalenský, Jan ; Krejsa, Jiří (referee) ; Březina, Tomáš (advisor)
This thesis is focused on the characteristics of a complete matrix, its application in physical analogies and exploration of suitable methods of computer generation of its cofactors. The opening section covers the key elements of matrix algebra, emphasising cofactors, and their attributes. The next segment examines the generalization of circuit theory for the purposes of multidisciplinary modeling and detailed analysis of a complete matrix and its properties. Finally, the previous findings and the characteristics of a complete matrix and its cofactors are applied to the deduction of elementary transfers, explained on examples and symbolically utilised in computer generation.

Coupled model of solenoid
Hejl, Karel ; Huzlík, Rostislav (referee) ; Vlach, Radek (advisor)
This work deals with the coupled model of an electromagnet and the verification of its results on a real electromagnet. The first chapter of this thesis is an introduction to the issues addressed in this work. The second chapter is devoted to physical analogies between domains and the description of an electromagnet. Also described are mathematical equations for electromagnet from electric, magnetic, mechanical and thermal viewing, as well as descriptions of modelling approaches using Matlab, Simulink and Simscape. The third chapter describes the design of an electromagnet to verify the coupled model. Another section is devoted to compiling equations for this proposed electromagnet and making of models. The penultimate part is dedicated to electromagnet design, measurement and data processing. The last section is devoted to comparing data with simulation and appreciation.
