DSP-Based on Brushless DC Motor Speed Control by PI Controller Using Back EMF Detection

Abstract

This paper presents a design and implementation of Brushless DC (BLDC) motor speed control based on the TMS320F28335 DSP board interfacing to MATLAB/SIMULINK. To obtain the optimal tracking and regulating responses, the PI controller is conducted and designed by pole placement technique. With Back EMF detection, the proposed system is considered as a class of sensorless control. This scheme leads to the speed adjustment of the BLDC motor by PWM. This experiment aims to examine the effectiveness of BLDC motor by testing the BLDC motor of 100 watt. It was found that the speed response of BLDC motor can be regulated at the operating speed of 700 rpm and 1400 rpm at no load and full load conditions.

A Novel Fuzzy Self Tuning Technique of Single Neuron PID Controller for Brushless DC Motor

“…Conventional control methods cannot achieve the desired speed tracking with good accuracy in case of sudden disturbance and parameters variation [4]. The PID controller is a linear controller and widely accepted because of its simple scheme and excellent performance.…”

“…The PID controller is a linear controller and widely accepted because of its simple scheme and excellent performance. It represents a good candidate for different industrial applications [4,5]. It is known by its elimination of the error in steady-state.…”
