Piecewise Modelling Approach for Specific Switched Reluctance Machines

Switched Reluctance Machine (SRM) is a very basic and simple electrical machine in structure with winding only at its stator. SRM has widely been considered for possible usages in modern aircrafts through the development of More Electric Aircraft (MEA). However, the nonlinear behavior of SRM results in difficulty in obtaining accurate model for simulation and development of its control system. A piecewise analytical modelling using inductance profile for a specific SRM is presented in this paper. The SRM used in this study is a specific custom designed 45kW 6/4 SRM which has unique electromagnetic characteristics. In this paper, the analytical model presented is compared against the measured values for accuracy.
