A Power Factor improvement and Speed Control of BLDC Motor Drive using ANFIS Controller
In this paper a comparative analysis of speed control of brushless DC motor (BLDC) drive fed with Voltage source inverter is achieved. The performance of the drive system is successfully evaluated using ANFIS based speed controller. Then the speed and torque characteristic of conventional two level inverter is compared with the various operating conditions. The inverters are simulated using IGBT's and the simulation results show that the ANFIS based speed controller eliminate torque ripples and provides fast speed response. The developed ANFIS model has the ability to learn both neural network and fuzzy control parameters based on disturbances with minimum steady state error, overshoot and rise time of the output voltage. The power factor correction of BLDC motor drive is done by using interleaved CSC converter and also it results shows the power factor is improved.
