Generalized model for a class of Switched Reluctance Motors

The paper deals with the problems of identification of a class of Switched Reluctance Motors (SRM). A generalized mathematical description of different SRMs with central geometrical symmetry of active poles is suggested. Convenient simulation cellular model of the motor is presented here that is of extreme importance in order to build up a proper SRM drive. The identification of Switched Reluctance Motors is rather sophisticated task due to the fact that the stator inductance depends on both position of the rotor and the stator current. The problem is further complicated due to the influence of the air gap and the highly nonlinear characteristic of the magnetic circuit. The mathematical model of the SRM is of a high order and is described by partial differential equations. In order to avoid this complex mathematical description, artificial neural network substitutions are utilized. They simplify the process of identification and make it easy - using Matlab Simulink. A suggestion for future work is also made in the paper.
