Parametric Identification of Mechatronic System with Induction and Synchronous Electric Drive

The greatest progress is observed in variable speed AC electric drives. The article presents principles and approaches to the synthesis of structures and parameters of corrective connections of AC electric drives with field regulated reluctance machine. It is shown that the quality of the control parameters depends on the conditions for setting the internal regulation loop of the electromagnetic torque. It is known that the parameters of electromechanical converters change in a wide range (2-3 times) and depend on the operating modes of the electric drive. The article draws attention to the algorithm of identifying the parameters of a high-speed loop of regulation electromagnetic torque using synchronous detection methods. This approach allows to define the parameters of the control object, compare the limit capabilities of different types of variable speed electric drives, estimate the range of changes in the parameters of the electrical machine, which is necessary for successful selection of the structure and parameters of the regulation structure.
