| Abstract | ||
| When driven by a filed oriented controller, an induction motor behaves like a separately excited DC machine where the torque and the flux are controlled independently. Based on the direct field orientation control induction motor (DFOCIM) model, the stator current ,rotor flux and rotor speed of induction motor are estimated simultaneously using linear Luenberger observer for stator current and rotor flux and Adaptive linear luenberger observer for stator current ,rotor flux and rotor speed. The salient advantage of the linear Luenberger observer is the accuracy of the observed stator current and rotor flux and that of Adaptive linear luenberger observer is the accuracy of the stator current, rotor flux and rotor speed observation. The validity of the proposed method is verified by the simulation results using matlab software. | ||
