A control system for a child swing that comprises a drive mechanism that includes a motor configured to impart torque to the at least one swing arm so that a child seat moves in an arcuate path. A phase control subsystem generates a motor drive signal configured to maintain a desired lead angle between a phase of the drive mechanism and a phase of the swing arm. An amplitude control subsystem configured to steer the phase control subsystem based on a correlation of an actual height of the child seat to a selected height of the child seat.

Control system for a child swing

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.
