| Abstract: | A full-order closed-loop rotor flux estimator was introduced into the direct field oriented control(DFOC) in an induction motor,and the observer precision affected by motor parameter was investigated.The normal current flux observer and voltage flux observer were compared by frequency response method.Amplitude-and-phase-frequency characteristic curve method of linear time-invariant system was used to simulate the parameter robustness of the proposed full order flux observer.The simulation results indicated ... |
