Fuzzy based direct torque and flux control of induction motor drives

“

This paper investigates direct torque and flux control of an induction motor drive based on the fuzzy logic (FL) control technique. Direct torque and flux control has become a widely acceptable alternative to field oriented control The hysteresis-band controller for the stator flux and the electromagnetic torque was designed using a fuzzy logic system. (FLS) in MATLAB. Simulation results show that the direct torque and flux control using an FL approach performs very fast dynamic response and has a simple structure which makes it to be more popularly used in the industry
