ABSTRACT:
An assist gradient Ra and also an F/B gain gradient Rp are inputted to an assist gradient compensation control unit. The F/B gradient Rp is added to the assist gradient Ra in an adder and the sum obtained is inputted into a switching control unit. The assist gradient Ra that has been inputted from a basic assist control unit is directly inputted together with the sum to the switching control unit. When a torque feedback control is executed, the switching control unit outputs the sum of the assist gradient Ra and F/B gain gradient Rp to a filter constant computation unit and an assist gradient gain computation unit.
