Kishor K, Akhil M K

Brushless DC Motors, by their high efficiency, high torque and low volume are increasingly used in many industrial applications. By taking it into consideration, a complete model of four quadrant control of BLDC Motor operation in association with GA optimized PID controller for its position control to obtain maximum speed operation is presented in this paper. The power supply to feed the windings of the motor is given by an inverter circuit. The gate drives to the switches of inverter is fed by space vector PWM technique in this paper for reducing the total harmonic index of the proposed system than the conventional existing methods. The MatLab/ Simulink are used in this paper to establish a model of four quadrant operation of BLDC motor.
