Title:
モータ駆動システムの制御装置
Document Type and Number:
Japanese Patent JP4706324
Kind Code:
B2
Abstract:
A square wave voltage having an amplitude equal to an output voltage (VH) of a converter (12) is applied to an AC motor (M1) by a square wave control block (400). Torque control of the AC motor (M1) is performed basically by changing the voltage phase (Æv) of the square wave voltage according to the torque deviation (Tq). When the motor revolution (Nmt) is suddenly changed, a VH instruction value correction unit (320) sets a voltage instruction value (VH#) of the output voltage (VH) of the converter (12) according to a change ratio of the motor revolutions. This improves control of the motor current by changing the voltage applied to the motor in accordance with the sudden change of the motor revolutions without waiting for torque feedback control having a low control response.
