A position control system, which has the torque varying with an angular position, often shows a Jerky output response with respect to a small velocity input, and this phenomenon is usually called a ”Jerking motion”. In this paper, as an approach to suppress such an undesirable phenomenon, the effect of a dither which is a relatively high frequency signal superimposed on the input signal is investigated.　By the use of a position control system with a commercial d-c servomotor, an experiment is performed for the effect of the dither on the Jerking motion. As a result, it becomes clear that the Jerking motion can be well suppressed by the dither and that the effective dither signal is limited to certain ranges in both amplitude and frequency.　By introducing a performance index for the wave form of the system response, the quantitative effect of the dither is investigated by analogue simulation. The experimental results are supported quantitatively by the simulation, and several properties of the effect of the dither on the Jerking motion are clarified.
