Speed Control of BLDC Motor Using Voice Command By Implementing Machine Learning

Abstract

The paper deals with the control of speed of BLDC motor drive in a closed loop control technique. NodeMCU is used as a microcontroller where machine learning program is implemented. According to the desired speed given by the user via voice command, the motor will run at the exact speed. Instead of using speed sensor, the stator back -emf is used to  estimate the rotor speed.
