Abstract:
A motor control device includes an inverter to drive a motor, and a control calculator to calculate a current command value indicating a current to be supplied to the motor from the inverter. The control calculator includes a voltage control calculator to calculate a voltage command value indicating a voltage to be applied to the motor from the inverter based on a current deviation between the current command value and the actual current detection value, and a compensation calculator to add a compensation value to a signal value on at least one of an upstream side and a downstream side in a signal flow that passes through the voltage control calculator. The voltage control calculator calculates the voltage command value by adaptive control based on an actual angular velocity value indicating an angular velocity at which the motor rotates. The compensation calculator calculates the compensation value based on the actual angular velocity value and the target current command value.
