Abstract
Disclosed is a three-phase AC induction motor control device for controlling a torque based on a two-axis orthogonal coordinate system in synchronization with a power supply angular frequency, the control device including: a non-interference controller configured to receive a motor rotation speed, a torque command value, and a power supply voltage as an input and compute a torque axis non-interference compensation voltage and a magnetic flux axis non-interference compensation voltage by referencing a map stored in advance; and a non-interference magnetic flux response filter configured to perform filtering, including a direct transfer term and a rotor magnetic flux response delay, for the torque axis non-interference compensation voltage.
