An Incremental Feedback Control for Uncertain Mechanical System.

This paper focuses on the tracking problem for fully-actuated mechanical systems with uncertain parameters and external disturbances. Based on the state feedback control of contraction analysis, the robust controller with extra gains is suggested to provide for the tracking of mechanical systems with uncertainties. The proposed control scheme can be redesigned with dual ideas and theoretically prove that the robust control renders uniform roundedness. Further more, the inertia matrices being uniformly bounded above are limited. The simulation is proposed to account for the effectiveness and robustness of the provided method.
