Self-synchronization and controlled synchronization: general definition and example design Original Research Article

A general definition of synchronization is given, capturing features of both self-synchronized systems and systems synchronized by means of external control. The definition is exemplified by a number of special cases, including frequency or Hugenii synchronization. A new solution to the important problem of controlled synchronization of two vibroactuators is given based on a speed-gradient method. Computer simulations of the designed synchronization system are presented.
