Pulse shaping of an impulse controller to improve precision of machines with friction

Conference Paper


Abstract


  • This paper investigates the effect of using force

    impulses of different shapes to control machines with friction to

    achieve more precise positioning and better low speed velocity

    control. It is shown that by shaping the pulses the smallest

    available movement of the servomechanism, can be reduced,

    and so it’s precision is enhanced. Several new force impulse

    controllers are investigated and their benefits, including

    improved precision and reduced machine vibration, described

    and experimentally verified. These benefits are achieved

    without mechanical modifications or any requirement for

    higher tolerance mechanical components, and the control

    scheme does not have to replace, but can be used to augment, a

    conventional PID controller.
