Fuzzy logic controlled Cuk converter-inverter fed induction motor drive with reduced torque ripple

Abstract

This paper deals with the modelling, simulation and implementation of a Fuzzy logic controlled Cuk converter-Inverter fed Induction motor drive. This work proposes PV fed Cuk converter to produce required DC voltage at the input of inverter. The output of the Photo Voltaic (PV) system is boosted using a Cuk converter. The output of the Cuk converter is inverted and applied to a three phase induction motor. Closed loop Proportional Integral Derivative (PID) and Fuzzy controlled systems are simulated and their responses are compared. The Fuzzy controlled drive system has advantages like reduced torque ripple and improved time domain response. The hardware is fabricated and the experimental results are compared with the simulation results.
