Mathematic model of steam turbine
Kroliczek, Filip ; Dokoupil, Jakub (referee) ; Pivoňka, Petr (advisor)
The goal of this thesis was to create a mathematical model of a steam turbine based on the data acquired by measurement, and to verify its behaviour. The first part contains research, which is supposed to introduce basic principles of the steam turbine and description of important construction parts and the possibilities of control. The second part describes the experimental identification method of least squares, used for the calculation of an ARX model of the steam turbine. Finally, the last part focuses on the program environment used for creation of the mathematical model and explanation of measured data analysis process. Furthermore this segment describes the created simulation program as well as a visualisation of the dynamic processes in the steam turbine, including the design of control.

Pre-processing of acquired data for system identification purposes
Horáková, Eva ; Chlápek, Petr (referee) ; Máša, Vítězslav (advisor)
The present bachelor’s thesis follows a methodology of data processing for the experimental system identification. Summarizes basic principles of experimental identification and describes a general methodology of experimental data processing. Next part of thesis attends to describing a building of compact data file, that contains selected variables including calculation of other important variables. Measurements to obtain experimental data was realized on real technology, which is a unit of biomass and phytomass combustion, power of unit is 1 MW. The work also includes selection and evaluation of appropriate intervals for an identification of this unit and their graphic presentation.

Parameter Identification of Induction Motor Equivalent Circuits
Karpenko, Oleksii ; Cipín, Radoslav (referee) ; Toman, Marek (advisor)
In the control of an asynchronous motor, it is important to determine the parameters of its replacement connection with the greatest accuracy. This work focuses on the identification of these parameters by various methods, which are represented in the form of a -network and a T-network. The bachelor thesis is divided into five parts. The first part focuses on the theory of the asynchronous motor, its use, distribution and properties. The second part deals with replacement connections of the asynchronous motor, their specifics and the possibility of its conversion. The third chapter focuses on the theoretical procedures of parameter identification using various methods as well as the theory of engine tests. In the last two chapters, the theoretical findings from the previous parts are experimentally verified on a real engine sample. Subsequently, the results obtained by different methods were compared with each other.
