Simulation and Design of Android Based Fuzzy Logic Variable Frequency Motor Drive

Abstract

With Advance technology things are becomes simpler and easier for us. Induction motor plays important role in industry and automotive application. There are different methods used to control the speed of induction motors, but conventional speed control technique are not that much effective. The aim of paper is to conserve the electricity and reduce the human efforts by making proposed model digitally controlled. Its operation is based on Arduino AT uno328 programming language. A Bluetooth terminal is interfaced to the ports of the Arduino. When user sent proportional value to a motor speed from Android phone thismessaged is thus fetched into the controller and it will generate the delay to each phase by using if else FUZZY LOGIC statement. Then thisgate pulses applied to TRIAC switches proportional with the sent value from Android phone. That will adjust the output voltage and frequency and IM runs at multiple speeds. The feedback path is used to keep the IM speed constant. It is further displayed on an electronic LCD display interfaced to Arduino.
