Abstract :
This paper presents a practical implementation of
a Genetic Algorithm (GA) based PID controller for high
performance Brushless DC (BLDC) motor. The purpose is to test
the ability of the proposed GA based PID controller to force the
rotor speed of BLDC motor to follow a preselected speed track.
Three different cost functions are used by GAoptimization
method to find the proper PID controller parameters. The
objective of the first cost function is to minimize the square error
while the objective of the second cost function is to minimize rise
time, steady state error, settling time and maximum over shoot
according to the priority of the designer. Moreover, the objective
of third cost function compromise between minimizing either the
maximum over shoot and steady-state error or the rise time and
settling time. The simulation and experimental results show that
the performance of genetic PID controller based on third cost
function has the best performance amongthese techniques.
