Speed Control of Brushless DC Motor Using Proportional Integral Controller
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 12
Abstract
Ease control and high power density are the two main reasons for using brushless DC motor in wide range of industrial applications. In general the brushless DC motors are controlled using power Semiconductor bridge. So the rotor position sensors are used in the inverter bridge for starting and to provide proper commutation sequence to the power switches. In building inverter bridge power switches are used due to high reliability and performance. In this paper the three phase brushless DC motor model is designed with proportional integral controller and tested in MATLAB software. The PI controller is used to control the speed of the brushless DC motor. On the other hand parameters like Back EMF, current, speed and torque are evaluated for the designed models of BLDC motor. Due to the easy implementation and simple control structure the convectional PI controller are used in industries.
