Characteristics and performance of BLDC motor under different loads in EV applications

The emerging operating technology of perfect operation in BLDC motor drive system can be analyzed and compared with Fuzzy-Proportional Integral Derivative (Fuzzy-PID) controller and the newly proposed Adaptive Neuro Fuzzy Interface System-Proportional Integral Derivative (ANFIS-PID) controller. It is observed that the changes in input parameters and load variations have large impact in the usual operation of the BLDC motor. A suggestion has been recorded in this research by noting the dynamic speed reaction of the BLDC motor by the action of apply and removal of sudden and gradual load respectively. Generally the BLDC motor faces jumpy nature problems while removing the loads in the Electric Vehicle (EV) system. The performance of the suggested controller, ANFIS-PID has been validated in terms of rise time, settling time and peak overshoot of the BLDC motor.
