This paper describes nonlinear vibration and control of a vibratory machine which has a large work mass. Vibration of the vibratory machine and movement of the work are coupled through normal force and friction force. The coupled vibration is nonlinear, and a resonance curve in small excited voltage has a peak in low frequency region and a resonance curve in large excited voltage has a peak in high frequency region. Self-excited vibration occurred by positive feedback of vibratory velocity excites vibratory machine and follows the resonance frequency change automatically, and it improves machine efficiency. Amplitude control using variable feedback grain starts up self-excited vibration quickly and stops too, and makes to adjust amplitude of a vibratory machine possible .
