Abstract
A control system for a child swing that comprises an amplitude control subsystem configured to use one or more electrical signals from a swing sensor to compare an actual amplitude of the child swing to a pre-set amplitude of the child swing to generate an adjustment signal representing a desired adjustment to the phase of the drive mechanism. The child swing also comprises a phase control subsystem configured to use an electrical signal representative of a phase of the drive mechanism and the adjustment signal to generate a motor drive signal configured to cause the desired adjustment to the phase of the drive mechanism.
