Abstract : A controller is provided for driving at least two systems in synchronization with one another. The controller provides a pseudoperiodic drive to drive the two systems at a desired frequency and to ensure that the two systems are synchronized. The pseudoperiodic drive can be produced by combining a periodic drive with a chaotic drive, noise drive or an incommensurate frequency drive. Any of these types of drives can be combined with the periodic drive by adding to or modulating the periodic drive. Thus, the controller can drive the two systems in phase with one another by using the same pseudoperiodic drive.
