Speed & torque vector control of induction motors with Fuzzy Logic Controller

Abstract

This paper presents a hybrid fuzzy logic controller (FLC) with vector-control method for induction motors. The vector-control method has been improved by using FLC instead of a simple PD controller. In this hybrid controller high quality regulation is achieved through utilization of the FLC, while stability of the system during transient and around wide range of operating points are assured through application of the vector-control. The hybrid controller has been validated by applying it to a nonlinear model of the motor.
