초록

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.
