The trajectory tracking control of 3-DOF instrument is very important for master-slave control robotic-assisted minimally invasive surgery. In this paper, dynamic structure and equation of motion for the 3-DOF instrument was established to use the Euler-Lagrange method based on screw theory. A control scheme is designed based on the computed-torque controller and a RBF neural network based compensating...
This paper addresses the issue of trajectory tracking control based on a neural network controller for industrial manipulators. A new control scheme is proposed based on neural network technology and linear feedback approach for tracking a planned trajectory. The control system is established with two parallel subsystems designed separately. One is a linear controller based on state feedback with...
An adaptive neural network controller is proposed to deal with the task-space tracking problem of manipulators with kinematic and dynamic uncertainties. The orientation of manipulator is represented by the unit quaternion, which avoids singularities associated with three-parameter representation. By employing the adaptive Jacobian scheme, neural networks, and backstepping technique, the torque controller...
