Motion control of the mechanical systems with visual feedback is a basic ability of human being. Appli cations that have been proposed widely span manufacturing, car steering and so on. Moreover, the visual feedback control is an important discipline that lies at the intersection between nonlinear control theory and geometric framework of the mechanics and image processing. This research deals with the visual feedback control of robotic manipulators in nonlinear control theoretical aspect.Firstly, the 3-D visual feedback control problem of the relative rigid body motion is considered as the stabilization problem with respect to the image feature position. By using the representation of SE(3), the relative rigid body motion dynamics between the target object and the camera has been derived. The passivity of the 3-D visual feedback system and the rotational matrix property derive the visual feedback controller to guarantee the asymptotic stability, in the Lyapunov sense.Next, the principal contribution of this research is the design and analysis of the isual feedback control via the nonlinear model predictive control. Based on the control Lyapunov function and the corresponding feedback control law, the stabilizing nonlinear model predictive control scheme for the 3-D visual feedback system has been proposed. The proposed scheme has employed the cost function as a Lyapunov function for establishing stability.

具有视觉反馈的机械系统的运动控制是人类的基本能力。已广泛提议的应用阳离子跨越了制造，汽车转向等。此外，视觉反馈控制是一个重要的学科，位于非线性控制理论与机械和图像处理的几何框架之间的相交。这项研究涉及非线性控制理论方面的机器人操纵器的视觉反馈控制。首先，相对刚体运动的3-D视觉反馈控制问题被认为是相对于图像特征位置的稳定问题。通过使用SE（3）的表示形式，已得出了目标对象和相机之间的相对刚体运动动力学。 3-D视觉反馈系统和旋转矩阵属性的被动性得出了视觉反馈控制器，以确保渐近稳定性，在Lyapunov Sense中，本研究的主要贡献是通过非线性模型预测性控制对等值反馈控制的设计和分析。基于控制Lyapunov函数和相应的反馈控制定律，已经提出了3D视觉反馈系统的稳定非线性模型预测控制方案。所提出的方案已采用成本函数作为建立稳定性的Lyapunov功能。
