  • Adaptive control for tape laying head having natural path generation
    Patent number: 4750965
    Abstract: A tape laying machine for depositing composite tape on the surface of a mandrel having a tape laying head positionable in multiple axes by a linear interpolative feedback control in combination with an adaptive control. The feedback control receives a commanded position from a natural path part program and regulates motion of the tape laying head of the machine along a track which will not unequally tension the edges of the tape and which is highly reproducible. The adaptive control separately varies the motion produced along individual axes by the feedback control without changing the tracking path to ensure correct tape laying conditions.
