Abstract
The Switched Reluctance Motor (SRM) drive system is currently used in high performance applications, and is considered for use in critical aerospace applications where it is required to operate reliably under partial fault conditions. No accurate models currently exist for the prediction of the dynamic performance under fault conditions. In this work, a computer aided method to predict the performance characteristics of SRM drive systems under internal and external faults is presented. This method involves the use of two dimensional nonlinear finite element field analysis to extract motor parameters under steady state and fault conditions. These parameters are used in a lumped parameter state space model in order to predict the system performance. In addition, the effects of mutual coupling between motor phases, which are usually neglected, are evaluated and the effects of force fitting on the machine parameters are examined. The proposed models account for this coupling and are used to study both internal and external faults in order to identify the fa.ult tolerance of SRM drive systems. The analysis of the fault conditions utilizes an iterative approach to update the inductances in order to accurately include the effects of magnetic nonlinearities on the device performance during the fault conditions. The developed models are validated by comparison to experimental data.
