Since a slave manipulator with a high reduction ratio joint generally
has slow dynamics in comparison with a master manipulator in
telemanipulation systems, its control input is likely to be saturated
resulting in poor position tracking performance and deteriorated stability. This
paper proposes a force reflecting control scheme for telemanipulators with
a high reduction ratio joint, which can effectively compensate the
control input saturation caused by the high ratio gear reducer
at its joint. The proposed scheme is also shown to
guarantee the stability and provides an excellent position tracking performance
regardless of the saturation.
