“…All other modes of its operation are abnormal, which, in addition to the violation serviced by the electric drive of the technological process, in the most severe cases can lead to emergencies. For traditional electric drive systems, a lot of literature is devoted to these issues, for example [1]- [4] and others. The switched reluctance drive (SRD), which has been rapidly developing in recent years [5]- [8], has a number of specific features, therefore, the issues of eliminating the abnormal modes of its operation require special study.…”

The paper presents the results of studies of abnormal conditions in a switched reluctance drive (SRD) due to failures in control algorithms. It discusses one of the most common control algorithms for these drives without the use of sensors, which is simple and easy to configure. The practical application of this algorithm of control showed that various anomalous phenomena could occur in it, expressed, for example, in a sharp increase in the amplitude of the phase current of the motor, and violation of the switching mode. The reasons for these phenomena are not evident and hard to analyze due to the nonlinearity of this drive. To identify these causes and search for measures to eliminate them, we used simulation in the environment of MATLAB/Simulink. The adequacy and effectiveness of the application of the developed simulation models we confirmed by a comparison of the simulation results and the full-scale experiment on real equipment. Theoretical studies and simulation results are in good agreement with the experimental results.
