This paper describes synchronization and phase difference control of two vibratory systems in elliptical vibration machine. Each vibratory system has local feedback loop for generating selfexcited vibration. The driving by self-excited vibration follows the resonance frequency change automatically and it reduces energy consumption. Natural frequencies differ in each vibration system, and then the frequency of self-excited vibration also differs. Therefore elliptical waveform changes incessantly. To synchronize each vibration, the control system has the feedback loop of the mean of velocity in two vibratory systems. It causes entrainment phenomenon in the same frequency. And large gain in the synchronization control, reduces phase difference between two vibratory systems. Phase difference control by phase shift filter gives constant phase difference between horizontal vibration and vertical vibration. Synchronization control and phase difference control of elliptical vibration machine stabilizes elliptical wave, which is generated in natural frequency.
