Document Type and Number:
Japanese Patent JP7291578
Kind Code:
B2
Abstract:
To provide a control method of a rotary electric machine and a control system of the rotary electric machine capable of suppressing a decrease in a degree of freedom of current control supplied to each multi-phase winding in a multiplex multi-phase rotary electric machine in which a plurality of multi-phase windings are provided in a stator.SOLUTION: In a multiplex multi-phase rotary electric machine in which a stator is provided with a plurality of multi-phase windings, a control method of a rotary electric machine is for controlling an operation of the multiplex multi-phase rotary electric machine by supplying a voltage based on a voltage command value to each multi-phase winding. The control method includes the steps of: inputting for acquiring a rotation state parameter indicating the rotation state of a rotor of the multiplex multiphase rotary electric machine and a current detection value which is a detection value of a current supplied to each multiphase winding; estimating an inductance of the multiplex multiphase rotary electric machine based on the rotation state parameter and the current detection value; and calculating a voltage command value based on the rotation state parameter, the current detection value, and the estimated inductance.SELECTED DRAWING: Figure 1
