Review of Methods Determining the Speed Sensorless of Induction Motors

V.G. Makarov, V.V. Tambov

Abstract


The analysis of the state of work on the identification of parameters and variables of the electric drive is held. Analysis of the current state of variable frequency drive confirms the relevance of the research in this area. It is shown that certain benefits has a continuous gradient method of finding the minimum of a positive definite function from the discrepancies equations electric drive. Substantiated expediency parallel solution of the problem determining the speed sensorless induction motor and the identification of its parameters. For the identification parameters and determine the speed without sensors is proposed use the of the sensitivity function the asynchronous electric drive to change of parameters.
