Abstract

Induction motor is the horse power of the industry since long time ago due to its cheaper price, simple construction and maintenance free. The induction motor is increasingly popular when the speed of the motor can be control which make it speed variable. Popular controller that be used to control the speed of the Induction Motor is PI controller and also Fuzzy Logic Controller. These two controllers have its own problem which is for PI, it is easy to undergo overshoot and undershoot when in the transient state. PI controller also sensitive to parameter variation and load variation which is can reduce the performance of the Induction Motor. For FLC, the main problem is about its steady state error when in steady state conditions. So, in this research the objective is to applied Hybrid PI and FLC strategy for Induction Motor to make use of the advantage of both controllers. In this research, the method that been used is Field Oriented Control (FOC). FOC was developed in the early 1970s and made it feasible to control the,induction motor as a separately excited DC motor. The result of the performance between PI,FLC and Hybrid controllers have been discussed and the Hybrid PI and FLC have a better performance compare to other two controllers in the terms of speed performance, speed drop, rising time and also speed drop.
