Bezsensorové řízení BLDC motoru

Abstract

Diplomová práce je zaměřena na problematiku bezsenzorového řízení BLDC motoru pomocí Rozšířeného Kálmánova filtru. V první části je popsán proces implementace EKF pro odhad rychlosti a elektrického natočení rotoru. K určení odhadovaných stavů používá EKF nelineární model BLDC motoru a měření některých veličin zahrnujících šum. Druhá část práce se zabývá návrhem metodiky měření a odhadem kvality bezsenzorového řízení BLDC motoru. Nejlepších výsledků bylo dosaženo analýzou zvlnění celkového proudu vstupujícího do výkonové elektroniky motoru. V závěru práce bylo ohodnoceno několik algoritmů pro bezsenzorové řízení BLDC motoru.

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.
