BLDC Motor Control Using Simulink Matlab and PCI

Abstract

This paper presents the control of BLDC motor using Simulink Matlab and PCI as interfacing to hardware. The control based on six step method that have certain relations among rotor positions and winding currents. These relations convert to digital functions and simplify using K-Map. The result then implemented by basic digital elements on Simulink Matlab and used to trigger the inverter through PCI interfacing to produce six step waveform. Before feed to inverter, a PWM added to these signal as speed control of BLDC motor. Test experiment results show that the control can produce variable speed, voltage and current
