A robust force control based on continuous switching of local control rules

Abstract

A robust force controller based on dual-mode control by continuous switching is described. This controller is applied to an observer-based acceleration controller, which eliminates the disturbance imposed on a manipulator. The robustness of the controller against stiffness variation of objects is improved, and the asymptotic stability of the controller is proved using the Lyapunov function. Experimental results verify the validity of proposed method.<>
