Closed-loop Control of BLDC Motor in Electric Vehicle Applications

This paper presents the closed-loop control (CLC) simulation for Brushless Direct Current (BLDC) motor used in electric vehicle (EV) application. There are many methods available to control BLDC motor, here a comparative study between conventional and auto-tuned optimal controller method for PID is reported. To ensure the quality of work, the motor parameters are estimated from real-time motor by experiments and it is used in simulation to study its performance thoroughly. From this it is concluded that auto-tuned PID controller has good track efficiency in achieving the target speed, torque and current variations can also be reduced.
