Abstract
A motor-driven power steering control apparatus is achieved, which uses a small-amplitude pass filter, the filter filtering out a component having a small amplitude, to remove a steering component from dynamic state quantity such as a rotational speed signal, and to accurately extract only a vibration component having a small amplitude compared with the steering component, and controls the vibration component to be reduced.
