Abstract
This paper presents a description and the results of simulations and laboratory tests of proposed methods for dependent torque control in a Switched Reluctance Motor (SRM). The proposed methods are based on Dependent Torque Motor Control (Rising Slope), DTMC(RC), and Dependent Torque Motor Control (Falling Slope), DTMC(FC). The results of these studies were compared with those on the Classical Torque Motor Control (CTMC) method. Studies were conducted for each of the analyzed control methods by determining the efficiency of the drive and the RMS of the source current and analyzing the vibrations generated for each of the control methods. The harmonics of the phase currents, which caused an increase in the level of vibrations generated, were determined. The usefulness of the proposed methods for controlling SRMs was assessed based on simulations and experiments. Additionally, the natural frequencies of the stator of the tested SRM were determined by a simulation using the Ansys Maxwell suite. The levels of vibration acceleration generated by the SRM were compared for the considered control methods.

Summary
Switched Reluctance Motors (SRMs) belong to a group of machines with electronic commutation. Motor control according to the functions described by Formulas (1)–(3) caused a slight change in the shape of the phase currents and torques. Based on the simulation results, the question arises as to whether these ‘slight’ changes in the shape of the phase currents and torques affect the performance characteristics of the drive To check this, the latter part of this paper presents a simulation (Figure 7, Table 2) and experimental tests. Based on the simulation results, Energies 2021, 14, x FOR PEER REVIEWthe question arises as to whether these ‘slight’ changes in the shape of the phase c7uorfre1n9 ts and torques affect the performance characteristics of the drive
