Abstract:
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.

Claim (Index 19):
The control unit of the electric power steering apparatus according to  claim 18 ,\n wherein said control parameter is set small where said rack displacement or said virtual rack displacement is small, and said control parameter is increased as said rack displacement or said virtual rack displacement is increased.
