A DESIGN OPTIMAL PID CONTROLLER FOR SPEED CONTROL OF BLBLDC MOTOR

The Brushless BLDC (BLBLDC) motor speed driving systems have sprouted in various small scale and large scale applications like automobile industries, domestic appliances etc. This leads to the development in Brushless BLDC motor (BLBLDCM). The usage of BLBLDC Motor enhances various performance factors ranging from higher efficiency, higher torque in low-speed range, high power density ,low maintenance and less noise than other motors. The BLBLDC Motor can act as an alternative for traditional motors like induction and switched reluctance motors. PID controller is implemented with speed feedback loop and it is observe that torque ripples are minimized. Simulation is carried out using MATLAB / SIMULINK. The results show that the performance of BLBLDC Motor is quite satisfactory for various loading conditions. Brushless BLDC motor drives are typically employed in speed controlled applications.
