Abstract
Brushless DC motor (BLDC) has applications in various fields. These motors have special applications in Antenna’s positioner. Antenna’s positioner will help in tracking the missile, satellite and aircraft etc. To these antenna’s positioner, BLDC motor are connected through Gear reducer, which is used to rotate clockwise or anti-clock wise. Based on error generated from potentiometer these motors are need to rotate in required direction. BLDC motor can work continuously or intermittently. For antenna positioner both continuous or intermittent types are required. To improve the speed of response, proportional and integral (PI) controllers are connected. These controllers add gain and pole to system, which will help in improving system performance. DC chopper help in reducing torque ripple, with the help of Pulse Width Modulation technique (PWM). In this paper, BLDC motor which is current controlled and chopper fed is simulated using MATLAB/SIMULINK for antenna’s positioner.
