Title:
CONTROL APPARATUS OF AC ROTATING MACHINE
Document Type and Number:
WIPO Patent Application WO/2012/014526
Kind Code:
A1
Abstract:
A control apparatus of AC rotating machine comprises: a current detection unit (4) that detects currents flowing from a power converter (2) to an AC motor (3); and a control unit (1) that generates, from the currents detected by the current detection unit (4) and a torque command value, three-phase AC voltage commands for the power converter (2). The control unit (1) comprises: an observer (50) that calculates, on the basis of the detected currents and the voltage commands, an estimated magnetic flux value of the AC rotating machine (3); a current command calculator (10) that calculates, on the basis of the torque command and the estimated magnetic flux value obtained by the observer (50), rotational two-axis current command values; and a voltage command calculator (20) that calculates voltage commands on the basis of both the current command value obtained by the current command calculator (10) and the estimated magnetic flux value obtained by the observer (50).
