Research on the application of the modified Luenberger observer extended with simultaneous estimation of both winding resistances of the IM for detection and compensation of different CS failures.

Research on the application of the modified Luenberger observer extended with simultaneous estimation of both winding resistances of the IM for detection and compensation of different CS failures. This solution enables an accurate stator current reconstruction in the case of different CS faults. In contrast to solutions known in the literature, the proposed approach utilizes a single observer, which allows for improved performance while simultaneously reducing computational requirements compared to dual observers and multi-observers.The data used in this research are attached and contain the transient signals obtained from simulations described as follows:mea - 'measured' valuesreal - ideal values ​​(without measurement noise)emlo - values ​​estimated by the EMLO estimatorc - values ​​used in the control structure and observer - calculated based on measured and estimated valuesref - reference valuesIM - values ​​in the induction motor model
