Control optimization of a Doubly Fed Induction Machine

Fuzzy super twisting algorithm dual direct torque control of doubly fed induction machine

“…While the use of the FSOSMC controller give a good performance: Allows the speed to judiciously follow its different reference values with better transient response time. The improvement of the FSOSMC in terms of overshoot, settling time, this result is indicated in Table 1, the rejects of the load disturbance is very rapid with a negligible steady state error, and FSOSMC minimize the chattering effect in the flux and torque ripple compared to the results obtained in [6]- [10].…”

“…The traditional model of DFIM in the laboratory frame ( , ) is written is being as in ( 1) [6]. The parameters of DFIM shows in the appendix.…”

“…To decrease or increase the flux amplitudes , and the angular position , in each sector, two adjacent voltage vectors can be used. The voltage vectors control of , planes are shown in Figure 1 [6].…”

“…The DDTC suffers from disadvantages ofvariation in the switching frequency, flux and torque ripples. Recently methods have been proposed to resolve this drawbacks; some papers focus on control optimization of a DFIM [6], some paper focus on low-speed sensorless double DTC for DFIM [7], and other papers propose the introducingof fuzzy logic technique [8], [9], while [10] propose the artificial neural network in DDTC of DFIM. Nevertheless, there are a few difficulties that limit the use of these kinds of controllers, such as a variable switching frequency, torque and flux ripple.…”
