MOTOR CONTROLLER

PROBLEM TO BE SOLVED: To provide a motor controller capable of stably performing control operation without reducing responsiveness and followability even when a voltage command value is limited.SOLUTION: A motor controller comprises: a PI control unit which calculates a PI calculation value; a non-interference control amount calculation unit which calculates a non-interference control amount for non-interference control of a motor; an addition unit which adds the PI calculation value calculated by PI control means and the non-interference control amount calculated by the non-interference control amount calculation unit; a limiter which limits an addition result of the addition unit and outputs a limited control amount as a motor voltage command value; and a gain calculation unit which calculates a target current gain on the basis of a motor rotation angle speed and a prescribed gain map. The motor controller multiplies a dq-axis target current by the target current gain calculated by the gain calculation unit to limit the dq-axis target current of the motor.
