Real time speed control of induction motor using new generation DSP controller

Abstract

This paper is concerned with real time implementation of voltage/frequency (V/F) speed control method with the help of digital signal processor (DSP). This method is helpful in controlling the speed of induction motor drive which is fed via voltage source inverter. The speed control technique is implemented using a new generation digital signal processor TMS320F28335 with a high sampling rate to make it possible that it achieve good dynamics. The algorithm is designed using MATLAB/SIMULINK and converted into C language using Code Composer Studio (CCS) environment. The sine pulse width modulation (SPWM) control algorithm is proposed for 3 phase 3-leg IGBT voltage source inverter.
