In this paper, a hybrid fuzzy-PI controller has been introduced for induction motor (IM) speed drive. The space vector pulse width modulation technique is used to generate switching pulses for the inverter switching of IGBTs because of low THD for the output voltage. The approach is suitable to attain an optimum trajectory planning for the used hybrid fuzzy-PI to control the speed of the IM. The controller performance is evaluated using MATLAB/Simulink software and will be compared with the case of using classical PI control scheme. The mean absolute error of the IM speed response is used as a fitness function. The actual speed of an IM is compared with a reference speed. The error is given through hybrid fuzzy-PI and classical PI controllers, and their outputs are applied to control the voltage magnitude of the IM. The hybrid fuzzy-PI is also employed to tune and minimize the mean absolute error to enhance the performance of the IM in terms of changes in speed and torque. The results obtained from the hybrid fuzzy-PI control are compared with those obtained through classical PI controller. These results showed that the hybrid fuzzy-PI controller is better than the classical PI controller in all tested cases in terms of damping capability, and transient response under different mechanical loads and speeds.
