 note = {application/pdf, As a method which improves a step response in a servo system, this paper proposes to control a damping coefficient optimally. In the case where the performance index is given by the settling time, the following results are obtained : (1) the optimal step response can be realized by bang-bang control of a damping coefficient ; (2) the switching functions on the phase plane are given by straight lines. These are supported by the experiment using a hybrid computer},
