چکیده

The paper deals with a model of a switched reluctance motor (SRM) that can be used for the development of control methods for the electrical drives with the SRMs. The non-linear theory describing the behavior of the SRM is listed that uses differential equations including the electromagnetic equations, the electromechanical equations, and the motion equation. On the basis of this theory, there are designed function dependencies of important quantities that are used in the model of the machine. For the verification of the designed model, there was used a control structure using Lyons method that belongs to basic sensorless control methods of the SRM. The sensorless control allows the estimation of the rotor angle and speed. The method is suitable for the area of middle and higher speeds of the SRM. In the paper, there are presented simulation results that show important quantities of the SRM during start and speed reversation.
