Fractional Order PI? Controller Application for Limited Memory System

Abstract

In this study, the fractional order PI?controller has been realized for induction motor speed controlsystem with using dsPIC microcontroller which has a limited memory device. To computation of fractional orderintegral, the error function and the weight function data sets has been limited for using only last 50 data. Thislimitation has provided the fractional order controller to be used in the dsPIC microcontroller. The experimentsare realized by using different kp, ki and ? values for speed control. The results are presented in tables andfigures.
