Passivity-based Visual Force Feedback Control for Planar Manipulators with Eye-in-Hand Configuration

Abstract

This paper investigates visual force feedback control for planar manipulators with the eye-in-hand configuration based on passivity. The vision/force control is applied to horizontal/vertical direction for the environment which is thought as a frictionless, elastically compliant plane. We show passivity of the visual force feedback system which allows us to prove stability in the sense of Lyapunov. The L2-gain performance analysis for the disturbance attenuation problem is considered via the dissipative systems theory. Finally simulation results are shown to verify the stability and L2-gain performance of the visual force feedback system.
