Abstract :
This paper presents an online fuzzy tuning scheme for indirect field orientation (IFO) controlled induction machine drives. A fuzzy controller is used to regulate the speed, and another two fuzzy compensators are combined to correct detuning of field orientation. Since detuning effects of IFO induction machine drive are minimized by the new fuzzy control scheme, the machine can achieve good performance in terms of overshoot, steady state error, torque disturbance and variable speed tracking. Efficiency and torque/ampere capability are also enhanced. The results obtained by laboratory implementation are presented to verify the effectiveness of the proposed online fuzzy tuning scheme
