Title:
CONTROLLER FOR MOTOR AND ITS POSITION CORRECTING METHOD
Document Type and Number:
Japanese Patent JP3419239
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently control to drive by driving a motor based on direction information by a driving means.
SOLUTION: A substracter 14 subtracts a speed command value ωrcom from a rotor angular velocity rω, and outputs information of speed difference to a speed controller 6. The controller 6 regulates a q-axis current command value 11qcom so that the angular velocity ωr of the rotor of a motor 1 becomes a value ωrcom. A substracter 12 subtracts the q-axis current command value 11qcom received from the controller 6 from q-axis current from a 3 phase-2 phase converter 4 to obtain their difference, and outputs the difference information to a q-axis current controller 7. The controller 7 regulates a value of an output voltage V1q output to a 2 phase-3 phase converter 8 based on the difference information. The current component actually output from an inverter 9 can be controlled to coincide with the current command value 11qcom output from the controller 6 by this regulation.
