回転電機制御システム
Document Type and Number:
Japanese Patent JP7423480
Kind Code:
B2
Abstract:
To appropriately reduce torque ripples without generating control interference even in a rotary electric machine with fluctuating torque.SOLUTION: A rotary electric machine control system comprises: a basic current command setting unit 1 that sets a basic current command Idq* on the basis of a target torque T* of a rotary electric machine; a correction current command setting unit 6 that sets a correction current command Idqh* having a frequency corresponding to torque ripples; and a current control unit 2 that performs current feedback control to calculate a voltage command Vdq* that is a command value for a voltage to be applied to the rotary electric machine. The current control unit 2 comprises: a first current control unit 20 that controls a component of the basic current command Idq*; and a second current control unit 21 that controls a component of the correction current command Idqh*. A gain of the second current control unit 21 is set to be lower than that of the first current control unit 20.SELECTED DRAWING: Figure 3
