Integration on VVVF Drive System for Induction Motor Speed Control with Lookup Table

Abstract

This project describes the development of a Variable Voltage Variable Frequency (VVVF) system that control the speed of Induction Motor (IM). The target value of VVVF is implemented with the Lookup Table and with the Proportional Integral (PI) for speed control. The LookUp Table give the speed input to be independent control. Both simulation and hardware implementation have been conducted in order to observed the integration between them for generating a suitbale PWM signal to inverter. The results, show, this integration is able to control the IM speed based on the desired target value. Several tests speed at the IM during the reference are 1300rpm and 1500rpm where the real outputs are 1297rpm and 1499rpm. At the end it can be concluded that, the VVVF when combined with the lookup table has created an ecosystem for simple speed control that can be learn and understand by the student.
