Iterative regulation of an electrically driven flexible-joint robot with model uncertainty

摘要

Considers the set-point regulation control problem of rigid and flexible-joint electrically driven robots with model uncertainties and unknown payloads. The proposed control scheme is based on simple linear state and output feedbacks. The resulting controller can also be implemented in a case where the current signal is not measurable. Applications of the approach when the Coulomb friction forces are taken into account have also been considered.
