ABSTRACT:
The present invention provides a control apparatus for an electric power steering apparatus comprises: a steering assist command value calculating section; a current control section that calculates a voltage command value; and a motor driving section that drives a motor based on the voltage command value, wherein an assist power from the motor is applied to a steering system, the control apparatus is characterized in that an SAT measuring section, that inputs an angular speed and an angular acceleration of the motor, the steering assist command value and the torque signal therein so as to estimate an SAT, is provided, and the SAT obtained by the SAT measuring section is feedbacked to the steering assist command value via a feedback section composed of a phase compensating section and a gain section.
