Asenkron motorların iyileştirilmiş anahtarlamalı-GKF tabanlı alan yönlendirmeli kontrolü.

In this study, the speed-sensorless improved field oriented control (FOC)-based induction motor (IM) drive has been presented. In addition to the rotor fluxes and rotor mechanical speed required for speed-sensorless FOC, the load torque, the stator resistance, and the rotor resistance are estimated by the switching extended Kalman filter (SEKF) with improved memory requirement and design stage which use the measured stator currents and voltages as inputs. The performance of FOC is improved by the feedforward control of the estimated load torque. In addition, the estimation errors caused by the parameter variations are reduced with the estimations of the stator and rotor resistances. The proposed speed-sensorless IM drive is tested by challenging scenarios in simulations. The results obtained demonstrate that the improved FOC-based IM drive has a high performance.
