dcd.rar - This paper presents a new image-based visual servoing
(IBVS) controller named augmented IBVS for a 6-DOF
manipulator. The main idea of this controller is that it produces acceleration
as the controlling command. A proportional-derivative
controller is developed to provide the robot with the controlling
command. This controller can achieve a smoother and more linear
feature trajectory in the image space and decrease the risk that
the features leave the field of view. The developed control method
also enhances the camera trajectory in 3-D space. The stability of
the proposed method is fully investigated by using the Lyapunov
method and the perturbed systems theory. Experimental tests are
performed on a 6-DOF robotic system to validate the effectiveness
of the proposed controller. The performance of the controller is
compared with that of a conventional IBVS.,2014-11-14 09:40:00,下载34次
