Title:
ELECTRIC MOTOR CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/034291
Kind Code:
A1
Abstract:
In order to provide feedback on the basis of deviation in the primary magnetic flux when performing primary flux control, an electric motor control device (1) is equipped with: a first coordinate conversion unit (101) that converts a three-phase current ([I]) to a current ([i]) in a δc-γc rotating coordinate system; a first calculation unit (102) that determines a feedback item ([F]); a second calculation unit (103A) that determines a voltage command value ([v*])in the δc-γc rotating coordinate system as the sum of the feedback item ([F]) and a feedback item ([B]); a second coordinate conversion unit (104) that performs a coordinate conversion on the voltage command value ([v*]), thereby converting this value to a voltage command value ([V*]) in another coordinate system for the voltage applied to a rotary electric motor (3); and an integrator (106) that calculates the phase (θ) of the δc axis with respect to the α axis on the basis of a command value (ω*) for the rotational angle velocity.
