Abnormal modes of Rectifier-and-Inductor Electric Motor Drive in Sensor Control

Based on results of MATLAB simulation of switching processes in rectifier-and-inductor electric motor drive, abnormal phenomena are studied which occur in the drive due to the sampling of control signals and the technological scatter of drive phase parameters. Quantitative estimations of the drive phase current amplitude deviations from the design values are presented together with recommendations for the deviations decrease. Theoretical results are confirmed by experimental studies.
