Mathematical Modelling And Position Control Of Brushless Dc (Bldc) Motor

摘要

The aim of the paper is to design a simulation model of Permanent Magnet Brushless DC (PMBLDC) motor and to control its position. In the developed model, the characteristics of the speed, torque, back EMF, voltages as well as currents are effectively monitored and analysed. The PID controller is used to control the position of a Permanent magnet brushless DC motor by changing the current flow to control the average voltage and thereby the average current. Most useful application is in controlling of CNC machine
