Fuzzy Speed Regulator for Induction Motor Direct
Torque Control Scheme
International Journal on Electrical and Power Engineering, 1 (3):
6 (December 2010)Abstract
This paper presents a novel design of a control
scheme for induction motor as a fuzzy logic application,
incorporating fuzzy control technique with direct torque
control method for induction motor drives. The direct torque
control method has been optimized by using fuzzy logic
controller instead of a conventional PI controller in the speed
regulation loop of induction motor drive system. The
presented fuzzy based control scheme combines the benefits of
fuzzy logic control technique along with direct torque control
technique. Compared to the conventional PI regulator, the
high quality speed regulation of induction motor can be
achieved by implementing a fuzzy logic controller as a PI-type
fuzzy speed regulator which is designed based on the
knowledge of experts without using the mathematical model.
The stability of the induction motor drive during transient
and steady operations is assured through the application of
fuzzy speed regulator along with the direct torque control.
The proposed fuzzy speed regulated direct torque control of
induction motor drive system has been validated by using
MATLAB simulink.
