Abstract
The article discusses the choice of control parameters for regulating various modes of operation of a switched reluctance motor. The analysis of articles published during the 2005-2018 year a switched reluctance motors for various drives in Ukraine and abroad. The analysis showed that there is a great diversity in the choice of control parameters from different authors, and most authors do not have an analysis of transients when using selected control parameters. The author of the article in previous works used phase control for a switched reluctance motor of a mine electric locomotive with a capacity of 27 kW and a rotational speed of 1146 min-1. In order to select the optimal control parameters in this work for the specified engine, the PWM voltage was chosen as the control parameter. Transients are considered when changing the load torque in the engine mode, as well as from the engine mode to the recuperative braking mode at a constant rotation speed using the developed engine model for transients in the Simulink program of the Matlab software package. When switching from engine mode to recuperative braking, the on and off angles changed. The pulse duty rates in PWM were determined using mechanical characteristics calculated on the engine models for steady-state conditions. The results of the analysis can be used in the de-velopment of a program for the microprocessor controller.
