Abstract
Stepper motors are found in three main types; Permanent Magnet, Variable reluctance and
Hybrid stepper motors. This paper concerns with the study of response of the PM stepper
motors using different two types of controllers. The position tracking of the PM stepper
motor is investigated on open loop and then PID and FLC are used to modify the open loop
response. The stepper motor is simulated with application of controllers using MATLAB
software. Controller is used to improve the motor performance by reducing the rise time,
minimize overshoots and eliminate the steady state error. The results show the advantages of
FLC over the conventional PID controller.
