Dynamic Behavior of Brushless DC Motor under the Application of PI, PD, PID, and Fuzzy Logic Controllers

ABSTRACT

The importance of Brushless Direct Current

(BLDC) motors in modern day technology cannot 

be overemphasized. Its improved performance in 

terms of efficiency, reliability, noise and dynamic 

response, better speed versus torque 

characteristics, higher speed range, and durability 

over the Brushed Direct Current motors could not 

be wished away.

This work investigates the performance of a BLDC

motor with the application of PI controller, PD 

controller, PID controller, and fuzzy logic controller

(FLC). Of paramount importance under the BLDC 

performance analysis are the rise time, the 

stability time, and sensitivity to error. Results from 

these analysis reveal that fuzzy logic controlled 

BLDC has a global performance acceptability over 

other considered controllers such as; Proportional 

Integral (PI), Proportional Derivative (PD), and 

Proportional plus Integral plus Derivative (PID).

This work is modeled and simulated using 

Matlab/Simulink software.
