Design of Drive System for Sensorless Brushless DC Motor Based on Model Reference Adaptive Control and Its Application in Horizontal Well TractorDOI: 10.4236/oalib.1104267, PP. 1-14 Subject Areas: Electric Engineering Keywords: Horizontal Well Tractor, Brushless DC Motor (BLDCM), Position Sensorless, Model Reference Adaptive Control (MRAC) Abstract
The
actual working environment temperature of the horizontal well tractor is too
high, which leads to position sensor of
general brushless DC motor (BLDCM)
cannot work normally. Therefore, the position sensorless drive system is
designed to overcome the problems caused by the position sensor in the actual
working conditions. The principle of sensorless BLDCM work is introduced in
detail, And drive system of Sensorless BLDCM was established by using simulation software. The use of three
stage start make motor smoothly start, the motor speed detection based
on model reference adaptive control
(MRAC), ensures accurate commutation. Finally, the
hardware and software design of the BLDCM system based on digital signal
controller (DSC)
is introduced and tested. The experimental results show that the drive system
can start the BLDCM smoothly in the high temperature environment, and can
quickly track the given speed,
which meet the actual work demand of the horizontal
well tractor.
