Abstract
Consideration of the magnetization of an induction machine for the implementation of energy-optimal control
Incoming article date: 24.05.2020This paper describes the methods used to take into account the nonlinearity of magnetic processes in the steel of an electric asynchronous machine. This is required for some cases when these physical processes play an important role in the accuracy of data. Justifications are presented that prove the need to approximate the magnetization curve of asynchronous machines to improve the quality of regulation of the electric drive, as well as improve control by energy criteria. Work at full load or near it leads to a decrease in the magnetization EMF due to a voltage drop in the stator, this must be taken into account. The article also shows the approach of applying the methods of accounting for saturation in synchronous machines for asynchronous using transformed equations.
