Abstract

The paper studies the merits of a 1-∅ induction motor powered by a Trina Solar's module TSM-250PA05.08 that employs the perturbs and observes (P&O) technique, utilizing two types of controllers, FOC and DTC. The merits of the two types of controllers were studied according to the results of the electromagnetic torque (Te), the currents of the main winding Ia and auxiliary winding Ib, and the Speed of a rotor. The results showed that both controllers' electromagnetic torque and speed rotor are very close. The results also showed distortions in the main and auxiliary winding currents when using the DTC controller. In contrast, when utilizing FOC, the results demonstrate smoother waveforms for main and auxiliary winding curves. Regarding response time, DTC achieves a faster rise time for Te and Ib than FOC. Also, concerning settling time, DTC achieves a faster settling time than FOC.
