Spectral method for motor parameters identification
Sedláček, Filip ; Buchta, Luděk (referee) ; Pohl, Lukáš (advisor)
This project deals with the problem of spectral method for system identification. Introductory part acquaints reader with basic concept of identification and explains its application in practice. It describes and mathematically derives two non-parametric methods for identification – correlation method and spectral analysis. The main aim of this final project is testing and implementation of spectral analysis in system parameters identification, which is specifically described in remaining sections of this project. These sections discuss a fundamental rules, procedures and principles in order to prepare a reader as much as possible for its final application in REAL-TIME system identification.

NVH Analysis of Transmissions
Gazda, Silvester ; Zubík, Martin (referee) ; Prokop, Aleš (advisor)
This bachelor's thesis deals with the design of measuring noise and vibration of vehicle transmissions. First describes the main parts of the transmission. This is followed by a description of sources of vibration and noise, and their travel. Significant work is devoted to analysis of the frequency spectrum, of its creation and evaluation. It also includes a description of the measurement and the necessary equipment, along with a description of the basic principles of its functioning.

Automatic signal evaluation using Fourier transform
Rudžík, Matej ; Zuth, Daniel (referee) ; Huzlík, Rostislav (advisor)
This master’s thesis deals with signal evaluation using Fourier transform. In the theoretical section, different methods of signal analysis with an emphasis on a Fast Fourier Transform are described. Theoretical section also contains description of common machinery faults and their diagnosis using frequency spectrum analysis. In the practical section, an algorithm for signal evaluation with an emphasis on coherence condition was designed in the Matlab environment. This algorithm was later used to evaluate submitted signals.
