Simulation of Energy Efficiency Improvement in Induction Motor Drive by Fuzzy Logic Based Temperature Compensation

Abstract

This paper proposes a method of improving efficient energy usage in induction motor drive system when operated under high temperature condition. By confining the drive signal to the prospective domain of that compensated by operating temperature range, an optimum point of driving performance and energy efficiency will be met for the given load torque and speed command. In this study, fuzzy logic has been applied as a temperature compensator and incorporated into the system model in MATLAB-Simulink. Simulation results showed that the system can operate and retain its performance together with efficient utilization of energy under high temperature condition.
