Abstract
A first-stage phase compensator, a second-stage phase compensator, and a third-stage phase compensator are configured in such a way that a frequency at which a phase calculated through the transfer function of the first-stage phase compensator becomes maximal and a frequency at which a phase calculated through a transfer function of the first-stage phase compensator and the third-stage phase compensator becomes maximal coincide with each other; a motor for generating assist torque is controlled, based on a torque signal to which the first-stage phase compensator, the second-stage phase compensator, and the third-stage phase compensator have applied phase compensation.
