3-PHASE MOTOR CONTROL DEVICE, 3-PHASE MOTOR SYSTEM, AND 3-PHASE MOTOR CONTROL METHOD AND PROGRAM

Document Type and Number:

WIPO Patent Application WO/2010/104059

Kind Code:

A1

Abstract:

A 3-phase motor control device (4) for controlling a driver for driving a 3-phase motor comprises: a target rotation angle generation unit (5) for generating a target rotation angle; an angle detector (2) for detecting a detection rotation angle that is the rotation angle of the 3-phase motor; a feedback controller (6) for generating, responsive to the target rotation angle and the detection rotation angle, a q-axis command reference value for controlling the q-axis voltage or q-axis current of the 3-phase motor (1); a drive torque correcting unit (7) and an adder (10) for correcting the q-axis command reference value to generate a q-axis command value; and a 2-phase/3-phase conversion unit (8) for generating a control signal that controls a driver circuit (3) for driving the 3-phase motor responsive to the q-axis command value. The drive torque correcting unit (7) has an angle reference table (11) for storing the values of parameters made correspond to the respective angle ranges of the rotation angles of the 3-phase motor and selects any of the parameters according to the detection rotation angle. Based on the values of the selected parameters, the q-axis command reference value is corrected to generate the q-axis command value.
