This paper presents model, scheme and performance assessment of speed control of PMBLDC motor with the help of PI controller. The PI 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. The speed is regulated by PI controller. Simulink is utilized, with MATLAB (2013a) to get a reliable and flexible simulation. In order to highlight the effectiveness of the speed control method used, the studies are conducted at two different load torques and the corresponding speed regulation is recorded using MATLAB/Simulink. The method proposed suppresses torque oscillations. This drive has high accuracy, high efficiency, silent operation, compact form, reliability, low maintenance, robust operation from near zero to high speed. Most useful applications in of CNC machine.
