Laboratory tasks for ball on an inclined plane
Řezáč, Martin ; Graf, Miroslav (referee) ; Blaha, Petr (advisor)
The thesis deals with the identification and control of dynamic systems using LabVIEW graphical programming environment. Cascade form of control with PI and PD controllers has been used for regulation and designed in Matlab. These controllers were then tested on real product. Laboratory exercises with model solutions are also included.

Supporting algorithms for electrical motor control
Řezáč, Martin ; Buchta, Luděk (referee) ; Blaha, Petr (advisor)
This thesis is focused on a creating supporting drivers and algorithms for electrical motor control using CPU TriCore TC275 CA. The first part is devoted to processor description and selected peripherals, which are A/D converter, a timer for creating the PWM signals and the second timer for processing singnals from encoder. All drivers are tested on an aplication kit, which is equipped with TC275 CA processor. The second part analyzes the measurement quality of GMR sensor TLE5009. Special testbench was prepared for sin cos data capturing and for their comparison with precise encoder position measurement. It was composed from DC motor having both sensor types on commons shaft. Data are acquired using LabView. Subsequently, it analyzes the sensor data, their compensation and subsequent comparison with measured data from the encoder.

Real-Time Analysis of Audio Signals
Řezáč, Martin ; Schimmel, Jiří (referee) ; Černocký, Jan (advisor)
The goal of this thesis is creation an application, which can perform real-time fundamental frequency tracking of incoming audio samples. According to detected frequencies, the program generates MIDI messages, which are sent to chosen MIDI device. First, the reader is introduced to the issue of fundamental frequency tracking. The following part describes individual methods, especially the one based on spectral analysis of a tone. A description of used technologies is also a included in this part of this thesis. In the following part, the implementation and testing of application are described including opinions of several musicians about this product. At the end, the whole work is concluded and the possible further development is outlined.

Parametrizable Music Instrument for Mobile Platforms
Řezáč, Martin ; Mlích, Jozef (referee) ; Černocký, Jan (advisor)
The goal of this thesis is to create an application, which will be primarily used as three-axis parametrizable musical instrument, respectively a modifi ed MIDI controller, suitable for Android devices. Firstly, several products, which are available on the market, are reviewed and the reader is introduced to the problematics of audio synthesis, available technologies and typical Android device potential. The next chapter is dedicated to application design. Few designs are mentioned with focus on the chosen design concept. A part of this chapter is also a speci cation of the original concept, its implementation and advantages/disadvantages. The next part is dedicated to implementation and optiomalization of some of the critical points. Also the tests are evaluated including a survey about application usability. At the end, the whole work is concluded and the further development is outlined.
