Title:
CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/133220
Kind Code:
A1
Abstract:
Demand exists for a device for controlling a rotary electric machine capable of reducing the tracking delay of the actual current and the actual output torque, as well as the steady-state error, in response to a pulsating torque command and electric current command. A control device for controlling a rotary electric machine drivably linked to an internal combustion engine and a wheel, wherein the control device is provided with a torque current computation unit for computing a two-phase current command on the basis of the torque command, an actual-current computation unit for computing a two-phase actual current, an electric current feedback control unit for changing the two-phase voltage command so that the two-phase actual current approximates the two-phase current command, and a voltage control unit operating on the basis of the two-phase voltage command. The torque command includes a pulsation-canceling torque command for the transmission torque pulsation transmitted from the internal combustion engine. The electric current feedback control unit has a harmonic controller for calculating the two-phase voltage command using the characteristic of a transfer function that corresponds to the periodic function of frequency of the transmitted torque pulsation.
