This paper presents a sensorless nonlinear control strategy for a doubly fed induction motor (DFIM) based on a combination of backstepping control (BS) and sliding mode observer (SMO) approaches. The main objective is to enhance the performance of field-oriented control (FOC) for DFIM by improving speed control performance, reducing electromagnetic torque ripple and improving stator current distortion, and achieving effective decoupling between torque and stator flux. The stability analysis of the proposed control strategy is conducted using Lyapunov theory. Furthermore, a sliding mode observer is designed to estimate the load torque and motor speed without needing additional sensors. The effectiveness of the proposed control strategy is validated by several simulation tests using Matlab/Simulink software. The results of the first test demonstrate remarkable improvements in response and steady state error of the speed control. Furthermore, the robustness of the designed control strategy is assessed, exhibiting superior performance in speed and torque control, as well as robustness against load disturbances and parameter variations. These findings highlight the potential of the proposed sensorless BS control strategy, with the sliding mode observer, as a promising solution for sensorless control of DFIM in diverse industrial applications.

W artykule przedstawiono bezczujnikową strategię nieliniowego sterowania silnikiem indukcyjnym z podwójnym zasilaniem (DFIM), opartą na połączeniu podejścia ze sterowaniem krokowym (BS) i obserwatorem trybu ślizgowego (SMO). Głównym celem jest zwiększenie wydajności sterowania zorientowanego na pole (FOC) dla DFIM poprzez poprawę wydajności sterowania prędkością, zmniejszenie tętnienia elektromagnetycznego momentu obrotowego i poprawę zniekształceń prądu stojana oraz osiągnięcie skutecznego oddzielenia momentu obrotowego od strumienia stojana. Analizę stabilności zaproponowanej strategii sterowania przeprowadzono z wykorzystaniem teorii Lapunowa. Co więcej, obserwator trybu ślizgowego ma za zadanie szacować moment obciążenia i prędkość silnika bez konieczności stosowania dodatkowych czujników. Skuteczność zaproponowanej strategii sterowania została potwierdzona szeregiem testów symulacyjnych z wykorzystaniem oprogramowania Matlab/Simulink. Wyniki pierwszego testu wykazują niezwykłą poprawę reakcji i błędu stanu ustalonego kontroli prędkości. Ponadto oceniana jest solidność zaprojektowanej strategii sterowania, wykazująca doskonałą wydajność w zakresie sterowania prędkością i momentem obrotowym, a także odporność na zakłócenia obciążenia i zmiany parametrów. Odkrycia te podkreślają potencjał proponowanej bezczujnikowej strategii sterowania BS z obserwatorem w trybie ślizgowym jako obiecującego rozwiązania do bezczujnikowego sterowania DFIM w różnorodnych zastosowaniach przemysłowych.
