摘要： In a preparation step, a frame (10), a concave spherical seat (15), a convex spherical seat (13), a rotation body (16), a rotating shaft (12), and a work holder (17) are assembled, a laser head (33) is attached to the convex spherical seat (13), and a light receiving unit (38) is attached to the work holder (17). In a rotation body centering step, an irradiation position of a laser beam (LB) with respect to a laser irradiation surface (41) is changed by rotating the rotation body (16) while allowing the laser irradiation surface (41) to be irradiated with the laser beam (LB) emitted from the laser head (33) and a trajectory of the irradiation position is checked.

摘要： [Problem]
An object of the present invention is to provide an electric power steering apparatus that easily obtains equivalent steering torques to vehicle driving information such as a steering angle without being affected by a road surface state and aging-changes of mechanism characteristics of a steering system.
[Means for solving the problem]
The electric power steering apparatus that assist-controls a steering system, comprises: a target steering torque generating section to generate a target steering torque based on vehicle driving information, a converting section to convert the target steering torque into a target torsional angle, and a torsional angle control section to calculate the current command value based on the target torsional angle, a torsional angle of the torsion bar and a motor angular velocity; and the torsional angle control section comprises a torsional angle feedback compensating section to output a target torsional angular velocity corresponding to a deviation between the target torsional angle and the torsional angle, a velocity control section to output the current command value based on the target torsional angular velocity, and a stabilization compensating section to perform feedback to the current command value by setting a transfer function to at least one of angle relation information.
