Abstract: “This paper compares the response of a induction machine with scalar speed PI controls and with Fuzzy logic controls. Fuzzy Logic Control is a part of intelligent control which contain hard and soft computing. The method uses a new linguistic rule table to adjust the motor control speed, and this FLC can achieve a good system performance of the IM scalar drive, and it is possible to implement a PI fuzzy logic controller instead the traditional PI controller. Hence, improvement can be achieved by the induction machine changing controls PI into Fuzzy.”

Keywords: Fuzzy logic controller, PI controller, induction motor.
