Abstract
The application background of the switched reluctance starter/generator (SR S/G) system is briefly introduced. The performance requirements of the system are presented, and then the structure and dimensions of an undergoing 30kW switched reluctance machine (SRM) are described. Based on these works, the optimal control strategies of the SRM are studied: on the starting stage of the engine, the switched reluctance machine operates as a motor, the maximization of its average torque is chosen as an optimization objective. Analytic, numerical and floating angle methods of choosing optimal exciting angles are considered respectively and compared with each other in detail. On the generating stage, the switched reluctance machine operates as a generator, the maximization of its efficiency under certain output power rating is chosen as an optimization objective, and the optimal exciting angles to minimize the main losses are obtained.
