This paper describes synchronization of two self-excited vibratory machines with local velocity feedback. In vibration transportation by decentralized vibratory machines, the resonance frequency of a vibratory machine varies with the movement of a work. Self-excited vibration by positive velocity feedback follows the resonance frequency change automatically in individual machine. The frequency difference of two vibratory machines stops transportation and makes large noise. The synchronization control has the feedback loop of the average of velocities in two vibratory machines. For small gain in synchronization control, local control has positive velocity feedback, and self-excited vibration is generated in resonance frequency. For large gain, local control has negative velocity feedback to suppress forced vibration by synchronization control, and then two vibratory machines vibrate in the same frequency. Synchronization of two vibratory machines realizes quiet and smooth transportation.
