The vibration with collision has essentially an uncertainty of steady-state motion for the impact phenomenon. If an unadjustable excitation like a harmonic force acts upon the system, existence of unstable motion cannot be avoided in the motional property. The difficult point is improved by adjustment of excitation according to the motion. Perturbation of the motion disappears by self timing control of the excitation, then the transient motion can return to the steady-state motion. The problem analytically investigated involves steady-state self-excited vibration with impact, which applies intermittently rectangular pulsive force train by self switching of constant force. The paper presents estimation of impact ability by energy supplied dissipation over a period of the motion which contains the only one shot. When both the switch on position of the pull up force and the switch off position of the pull down force are agreement with the height of impact position, the energy decreases. There is the practical optimum condition that minimizes for the energy in the case of, the drive by pull up and down forces, the bipolar drive.
