Key Points

Develop a robust sensorless control strategy for five-phase induction motor drives that mitigates chattering and resists parameter variations.
Integrated an extended third-order super-twisting sliding mode speed controller (TOSTSMSC) within a direct field-oriented control (DFOC) framework.
Implemented a hybrid model reference adaptive system coupled with an adaptive sliding mode observer (MRAS–ASMO) to estimate speed without physical sensors.
Conducted dynamic simulations to evaluate control performance under rotor resistance variations, thermal effects, and model mismatches.
The TOSTSMSC achieved finite-time convergence of speed errors while significantly attenuating high-frequency chattering compared to first- and second-order sliding mode designs.
The hybrid MRAS–ASMO scheme enabled accurate online rotor resistance adaptation, maintaining robust speed tracking despite temperature-induced parameter drifts.
The combined DFOC–TOSTSMSC–MRAS–ASMO architecture delivered superior dynamic response, reliability, and robustness compared to conventional PI and lower-order sliding mode controls.
