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.
