MOTOR CONTROLLER, AND MOTOR CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To provide a motor controller and a motor control method capable of reducing the vibration caused by a motor even in a condition of low speed and high torque which are caused by an angular speed feedback of non-interference control.

SOLUTION: The controller generates a voltage command value Vd*from a current command value, for feed back control using a detection current that flows in a motor. It includes non-interference control part 38 which multiplies a current (Iq*) representing a current that flows in the motor by a gain of a feedback control system which is a function that increases as an angular speed ω of the motor rises, and adds the product to the voltage command value Vd*.
