Abstract
Brushless Less DC motors has a specific characteristics
like high starting torque, high efficiency and
it has long life it has also termed as permanent magnet
synchronous motor. Due to the construction that suitable
for the critical application it is widely used in the industrial
area. By comparing BLDC motor with the induction
motor and DC motor it has several advantage such as long
life and no need of mechanical commutation. In order to
make the system stable in these project we have used the
Proportional Integral Derivative controller and the fuzzy
logic controller. In the BLDC Motor for giving the gate
signal the angle value of theta is given. In order to find the
error in the output side the feedback controller is used and
it is directly connected to the multilevel inverter for getting
the desired output the feedback is given to input. By using
the MATLAB Simulation the BLDC motor characteristics
such as back emf, speed, current has been determined.
Keywords: BLDC motor, Fuzzy logic controller, Inverter circuit model, PID controller.
