AbstractIn This paper, the indirect field vector control of induction motor (IM) which is controlled by an adaptive Proportional-Integral (PI) speed controller is proposed. The proposed solution can overcome the rotor resistance variation, which degrades the performance of the speed control. To remedy this drawback, an adaptive PI controller is designed with gains adaptation based on fuzzy logic in order to improve the performances of IM with respect to parameters variations. The proposed control algorithm is validated by simulation tests. The obtained results shows the robustness towards the load torque disturbances and rotor resistance variation of the adaptive Proportional-Integral fuzzy logic control with respect to classical PI control, and adaptive control based on rotor resistance observer.
