Abstract :
In this article a controller with parallel architecture of Fuzzy tuned PID and PD controller is designed and
implemented for speed control of brushless DC motor. The proposed controller has only one fuzzy gain tuner to tune
the three gain parameters (kp, ki, kd). A classical PD controller will be placed in parallel to fuzzy tuned PID controller.
The proposed controller architecture with merits of the classical PD and fuzzy tuned PID will be a better alternative
for controlling the speed of a Brushless motor. The time domain specifications of BLDC motor, obtained using the
proposed controller with parallel architecture of fuzzy tuned PID and PD controller are compared with response
obtained PI controller and fuzzy tuned PID controller. The controller is tested with variable speed and variable load
conditions. The design of proposed controller is very simple and it is effective because very low settling time, it has
zero peak overshoot and zero steady state error.
