Abstract

This project main purpose to design a three phase inverter of BLDC motor. Brushless DC motor (BLDC) are gaining popularity mainly due to their high efficiency, good dynamic response and very low maintanance. The BLDC motor with trapezoidal waveform of back- EMF have been developed with position sensor which is hall effect sensor. Simulation model of the PI controller for speed control of BLDC motor are also presented. Beside that, conventional PI controller are widely used because of simple structure and easy for implementation. The performance of BLDC motor system is fed by hysteresis current controller with voltage source inverter (VSI). A simulation result analyzed the performance of BLDC motor and compared the performance between PI parameters and speed response in term of overshoot, rise time, and settling time. The modelling, control and simulation of BLDC motor have been done and were carried out by simulated using the MATLAB/Simulink software.
