<p>It is an obj ect to provide a control device that is directed to an electric power steering device using a motor having a small inertia moment and suppresses a vibration while reducing a resistance to and a delay in steering based on a detection signal of a rotation speed of a motor. Provided is a control device for an electric power steering device, for controlling an output torque of a motor for outputting an assist torque based on a steering-torque signal from a torque sensor for detecting a steering torque, the control device for negatively feeding back a correction signal based on a motor-speed signal from motor-speed detection means for detecting a rotation speed of a rotary shaft of the motor to damp a vibration at a natural frequency determined in accordance with a transfer characteristic from the steering-torque signal to the output torque.</p> |
