Advanced driving system of the three-phase DC motor
Hanuš, Radek ; Boušek, Jaroslav (referee) ; Háze, Jiří (advisor)
The main aim of this thesis is to design and develop a control unit for a three-phase direct current motor that will be able to maximize its efficiency. To accomplish this request a field oriented control combined with modified phase driving signals is used. The emphasis is put on the creation of a simple and unique solution as well as the ability to use this device in the single wheel wehicle, which previous bachelor thesis was focused on. The first part of this thesis lists some of commercially available and do-it-yourself solutions together with their attributes. The next part describes target motors and different options of how to control them. The third part focuses on the field oriented control, its individual parts and features, as well as the final solution. And finally the realization of the electrical part, firmware, PC application and necessary settings are described at the very end of the thesis.

Analysis of PMSM motor inverter behaviour
Buchal, David ; Kozovský, Matúš (referee) ; Blaha, Petr (advisor)
This master‘s thesis deals with the design of a software solution for the AURIX TC234 microcontroller by Infineon Technologies which enables a user to start sampling of the signal at any required moment. A sampling time should be set to the lowest possible value. This solution is then added to the application which is used for a field oriented control of the brushless direct current motor. The obtained values can be further used, for example, for analyzing the waveform of motor currents from which it might be possible to determine the condition of the transistor inverter.

Monitoring and Diagnosis Algorithms for Synchronous Motor Drives
Otava, Lukáš ; Glasberger, Tomáš (referee) ; Lettl, Jiří (referee) ; Václavek, Pavel (advisor)
Permanent magnet synchronous machine drives are used more often. Although, synchronous machines drive also suffer from possible faults. This thesis is focused on the detection of the three-phase synchronous motor winding faults and the detection of the drive control loop sensors' faults. Firstly, a model of the faulty winding of the motor is presented. Effects of the inter-turn short fault were analyzed. The model was experimentally verified by fault emulation on the test bench with an industrial synchronous motor. Inter-turn short fault detection algorithms are summarized. Three existing conventional winding fault methods based on signal processing of the stator voltage and stator current residuals were verified. Three new winding fault detection methods were developed by the author. These methods use a modified motor model and the extended Kalman filter state estimator. Practical implementation of the algorithms on a microcontroller is described and experimental results show the performance of the presented algorithms in different scenarios on test bench measurements. Highly related motor control loop sensors fault detection algorithms are also described. These algorithms are complementary to winding fault algorithms. The decision mechanism integrates outputs of sensor and winding fault detection algorithms and provides an overall drive fault diagnosis concept.

Computational Performance Of Arm Cortex M4 Andm7 Microcontroller On Motor Control Application
Otava, Lukáš
The paper is focused on a comparison of three microcontrollers from computational performance point of the view. The comparison is performed on motor control and fault detection algorithm code executed from microcontroller internal FLASH memory. This code contains more complicated mathematical functions. The computational performance is compared according to computational time on STM32F4, STM32F7 and SAM E70 microcontrollers. Another aspects (like core clock frequency, FLASH configuration, cache configuration, etc.) of microcontroller settings are taken into account in experimental results.
