Efficient Finite-Position-Set MRAS Observer for Encoder-less Control of DFIGs
2019 IEEE International Symposium on Predictive Control of Electrical Drives and Power Electronics (PRECEDE), 2019 This work introduces an efficient finite-position-set model-reference adaptive system (FPS-MRAS) estimator for sensor-less control of a doubly fed induction generator (DFIG) in a variable speed wind energy conversion system (WECS). The idea of the proposed FPS-MRAS is derived from the finite-control-set model predictive control (FCS-MPC) principle, i.e.

Core loss resistance impact on sensorless speed control of an induction motor using hybrid adaptive sliding mode observer [PDF]
Archives of Electrical Engineering, 2023 Induction motors (IMs) experience power losses when a portion of the input power is converted to heat instead of driving the load. The combined effect of copper losses, core losses, and mechanical losses results in IM power losses.
