Passivity-based iterative learning control for visual feedback system

Abstract

This paper investigates iterative learning control based on passivity for three-dimensional (3-D) visual feedback systems. Firstly, a brief summary of a visual motion observer is given. Next, a pose control error system for iterative learning control that has an output strictly passivity property is constructed. Then, iterative learning control for 3-D visual feedback systems is proposed. The transient response of the proposed control law should be improved because of the repeatability. Convergence analysis of the closed-loop system is discussed based on passivity. Finally, simulation results are shown in order to confirm the proposed method.
