摘要：This paper presents a simulation for three Phase Power Control Driver for BLDC Motor withSensorless Rotor Positioning System using MATLAB. This describes the procedure of deriving an easy model for thebrush less dc motor with 3-phase inverter system, speed regulator and current controller.In this paper sensing of rotor position is done by using comparision and calculation method. Here the actual speed ofBLDC motor is compared with the reference speed and the error signal thus produces, regulates the speed controller.This speed controller produces reference torque which is used to calculate reference current. Hysteresis currentcontroller regulates current within reference current. It provides the pwm gating signals to inverter. Now here inverteris used to drive BLDC motor accordingly. This BLDC motor is in a wide use today in various industries so it is veryimportant to improve its efficiency. So here represent a paper which shows the improvement in BLDC motor andreduces the manufacturing cost of drive.The most advantageous part of this project is that it determines the rotor position with simple calculations andcomparisons and does not use any sensor. The effectiveness of this method is validated by simulation results inMATLAB simulink platform.
