Abstract
This paper describes the generation of phase difference in elliptical vibration machine by mutual entrainment and control of transportation velocity. Elliptical vibration machine which has a horizontal vibratory system and a vertical vibratory system has local feedback loops for generating self-excited vibration. The driving by self-excited vibration, follows resonance point, and reduces energy consumption. The synchronization control using a Mutual entrainment generates phase difference between horizontal vibration and vertical vibration by cross feedback of velocity and displacement as synchronization control force. Transportation velocity also including the direction of positive/negative can be controllable by using this phase difference.
