BLDC Motor Driven Solar Powered Air-Cooling System

The Brushless DC motor is a reliable motor, which exhibits characteristics such as high torque to power ratio, high efficiency, compact size and lower maintenance due to brushless structure. Due to these merits, this paper proposes to develop a solar fedBrushless DC motor drivenair-cooling system, which can operate satisfactorily for longer time periods as compared to brushed motors. To ensure the constant speed of the Brushless DC motor, Proportional Integral controller is used. In addition, the controller parameters of Proportional Integral controllerare tuned with soft computing techniques such as Fuzzy logic, Artificial Neural Network and Adaptive Neuro Fuzzy Inference System to obtain the better performance in the proposed system. The performance of PV array and speed control of the BLDC motor for air cooling system is analyzedin MATLAB Simulink environment.
