A control unit of an electric power steering apparatus that configures a control system on the basis of a physical model of a rack (steering rack) mechanism, configures a model following control where an output of a controlled object follows an output of a reference model, makes a driver feel an appropriate reaction force, and suppresses uncomfortable feeling to the driver by pulling-tendency, is provided. The control unit of the electric power steering apparatus that assists and controls a steering system by driving a motor based on a current command value, includes a configuration of a model following control setting a viscoelastic model for a rack displacement as a reference model, performs a feedback control which inputs a shaft force corresponding to a road surface reaction force, and generates a virtual reaction force, by the configuration of the model following control.
