| Abstract: | For improving stator flux observer,a RBF neural network stator flux observer is presented.A variable cutoff frequency stator flux estimator with amplitude and phase compensation was reconstructed with RBF neural networks,and the cutoff frequency of observer can vary with the stator voltage frequency changes.With variable cutoff frequency,simple structure,and better adaptive capability,without the problem of DC offset and initial phase,the RBF neural networks observer can accurately estimate motor stator flu... |
