Control of hot air tunnel
Šimurda, Jan ; Buchta, Luděk (referee) ; Blaha, Petr (advisor)
This bachelor thesis is dealing with the reconstruction of hot-air tunnel model for ma- nagement using CompactRIO system from National Instruments company. For a com- munication with the tunnel has been designed a user interface that guides a user through the system identification and controller design, which is testable as a simulation and then on a real device. The result of this thesis is to create a school task implementing the particular procedures.

Frequency method for motor parameters identification
Zimmert, Martin ; Buchta, Luděk (referee) ; Pohl, Lukáš (advisor)
This bachelor´s thesis deals with improved frequency method for motor parameters Identification. The goal of this thesis is to get an overview about identification method and simulate it on motor model in the Simulink and then to verify functionality of the method on the real motor. Firstly there are informations about a motor with permanent magnets and its control. Then there is an application of identification method for complete motor model. In the next part is measurement of the real motor. In the end is design of controller and discrete filter of identification signal.

Stepper motor feedback control
Mach, Martin ; Buchta, Luděk (referee) ; Blaha, Petr (advisor)
Goal of this thesis is to familiarize your-self with NCV70514 stepper motor driver by ON semiconductor, the function of bipolar stepper motor, hardware and software equipment developed for driving of NCV70514 and to explore possible algorithms for current and velocity adjustment to load by the means of back EMF. A simulink model was created for verification of said algorithms. The output is theoretical analysis and outputs of simulation. Futher more is to implement such algorithms in said microcontroler a then create graphic user interface running under Windows OS.

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.

Control and visualization of techlologic process via IPC
Buchta, Luděk ; Libor, Matys (referee) ; Dvořáček, Martin (advisor)
The aim of this bachelor’s thesis was to acquaint with techniques and technologies used in the control and visualization of technologic processes. The industrial PC, PLC and Automation Panels from the company B&R was used on control of the technologic process in laboratory E541. Designed and implemented control algorithm contains three discrete controllers. The standard OPC is used for communication. Visualization for control workplace is created in the Program Control Web. Visualizations for operator workstations are created in the program Automation Studio. These visualizations are used to transfer information from the technological process.

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.
