Research on Parameter Identification of the Stator Resistance Based on Wavelet Neural Networks

In this paper,a kind of WNN(wavelet neural network)is presented for resistance on-line identification.After trained with the R OLS(recursive orthogonal least square)algorithm,the network can be used to measure the value of resistance.Simulation results show that this detector can precisely measure the value of resistance and effectively improve the low-speed p erformance of DTC(direct torsion control)system.
