Offline and Online Modelling of Switched Reluctance Motor Based on RBF Neural Networks

摘要

Due to the highly nonlinearity of the flux-linkage characteristics of Switched Reluctance Motor drives (SRM), accuratelymodelling is cumbersome. In this paper, the offline- trained and the online-trained Radial Basis function (RBF) neuralnetwork model are proposed for estimating the SRM flux-linkage under running conditions. To investigate the performanceof the modelling schemes, the simulation and experiments have been implemented in a 12/8 structure SRM prototype. Theresults show that the online-trained model exhibits much better estimation accuracy and robustness than the offline-trainedmodel. Thus, the online-trained RBF model is more suitable for SRM performance prediction and analyzing.
