Passivity is an input–output property of dynamical systems. The concept generalizes
physical systems that cannot store more energy than the energy supplied from outside the …

摘要视觉伺服控制是机器人系统的重要控制手段. 随着机器人应用需求的日益复杂多样,
视觉伺服的研究面临着挑战. 视觉伺服系统的设计主要包括视觉系统, 控制策略和实现策略三个 …

In this paper, visual servoing based on photometric moments is advocated. A direct
approach is chosen by which the extraction of geometric primitives, visual tracking and …

The direct use of the entire photometric image information as dense features for visual
servoing brings several advantages. First, it does not require any feature detection …

The advantages of using the entire photometric image information as visual feature are: it
does not require any feature detections, matching or tracking process. To enlarge the …

Visual servoing based on photometric data is of great interest since it does not necessitate
any image processing or visual tracking steps. A vital issue in such methods is the change in …

In the process of satellite assembly, there are errors in the installation and positioning of the
cabin board and the frame, which leads to the deviation between the position of the screw …

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 …

Visual Servoing is generally contained of control and feature tracking. Study of previous
methods shows that no attempt has been made to optimize these two parts together. In …

This paper investigates stabilizing receding horizon control via an obstacle avoidance
navigation function for three-dimensional (3-D) eye-to-hand visual feedback systems. Firstly …
