OFFLINE AND ONLINE MODELING OF SWITCHED RELUCTANCE MOTOR BASED ON RBF NEURAL NETWORKS

Jun Cai – Zhiquan Deng

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

Keywords: offline modeling, online modeling, RBF neural network, flux-linkage, switched reluctance motor (SRM)
