Sensorless control of BLDC motor
Hrbáč, Zbyněk ; Grepl, Robert (referee) ; Sova, Václav (advisor)
This thesis is focused on the sensorless control of BLDC motor using the Extended Kalman filter. In the first section, process of EKF implementation for estimating rotor speed and electrical angle is described. For this estimation, EKF uses non-linear BLDC motor model and some measurement containing random noise. Second part deals with designing methodology to measure and estimate the quality of BLDC motor sensorless control. Best results were achieved with total current entering power electronics ripple analyzation. In the last section, several BLDC sensorless control algorithms were evaluated.

Gasoline generator for mobile robotic applications
Hrbáč, Zbyněk ; Lamberský, Vojtěch (referee) ; Vejlupek, Josef (advisor)
This bachelor’s thesis is focused on the construction of generator for mobile robotic applications. The first part provides a survey of power generators available on both the domestic and international markets. In the second part is an overview of applicable electrical machines in the generator mode. There is a description, principle of operation and specifics of each motor and a possible regulation of an output. The third part deals with the actual construction of a testing model. The BLDC (brushless DC) motor with output power of 660W was used as a generator.
