Provided is a control device for an electric power steering device, the control device configured to control an output torque of a motor that provides an assist torque to a steering torque, the output being controlled based on a steering-torque signal from a torque sensor that detects a steering torque, the control device controls the output torque using a correction signal to damp a vibration at a natural frequency determined in accordance with a transfer characteristic from the steering-torque signal to the output torque.

Electric power steering control device

A control device for an AC rotating machine includes a voltage command calculation means () that calculates voltage commands on rotation two axes and a voltage applying means () that applies a voltage to an AC rotating machine (), based on voltage commands on the rotation two axes outputted by the voltage command calculation means (); the voltage command calculation means () calculates first-axis and second-axis voltage commands on the rotation two axes and reduces the limit value of the second-axis voltage command in proportion to the squared first-axis voltage command.
