Abstract
One aspect of the present invention provides a testing apparatus comprising: an input-side drive unit capable of rotating a steering shaft that serves as a control device for a test object; and a control unit controlling the input-side drive unit to rotate the steering shaft according to a predetermined test waveform. The control unit is configured to execute a reversal control that immediately reverses the rotation direction of the steering shaft when the angular position of the steering shaft reaches a contact position that is the end of the movable range of the steering shaft. The reversal control includes a jump process that, when the angular position of the steering shaft reaches the contact position, jumps to the next control point where the torque is expected to be of the same magnitude as at that moment.
