Pure 2D visual servo control for a class of under-actuated dynamic systems

Abstract

A pure image-based strategy for visual servo control of a class of dynamic systems is proposed. The proposed design concerns the dynamics of unmanned aerial vehicles capable of quasi-stationary flight (hover and near hover flight). The visual servo control task considered is to locate the camera relative to a stationary target. The paper extends earlier work, by weakening the assumption on the construction of the visual error used. In prior work some inertial information was used in the error construction to guarantee the passivity properties of the control design. In this paper the visual error is defined purely in terms of the 2D image features derived from the camera signal. Show more
