Abstract

PURPOSE:To enhance the operation accuracy under the rotating conditions, by correcting and controlling the result of the magnetic-flux operation by a current model with the result of the operation by a voltage model, and by making it possible to operate under the stationary conditions of a motor. CONSTITUTION:Armature voltages are converted into components of an alpha- and beta-axis coordinate system by a coordinate converter 525. The converted values and the outputs of a pole-position operator are given to a coordinate converter 526, which in turn outputs the components of d- and q-axis coordinates system. Furthermore, induced voltages ed' and eq' are output from induced-voltage detectors 527 and 528. While, the outputs from the magnetic-flux operator in a current model are supplied to differentiators 533 and 534, and to multipliers 531 and 532 to which rotation speeds are input, and added to the induced voltages ed' and eq'. The resultant values are added to the outputs of the multipliers of the current models through adjusters 529 and 530. Therefore, the operation results by the current model can be corrected by the voltage model, thereby the operation accuracy can be greatly enhanced.
