چکیده
Support of this work by the NTUA Senator Committee of Basic Research, Programme “Protagoras”, R.C. No. 10, is acknowledged. Abstract− This paper addresses the combined problem of trajectory planning and tracking control for underactuated AUVs moving on the horizontal plane. A reference feasible trajectory for the position and orientation of the AUV is planned so that it is consistent with vehicle dynamics. Using these reference values the dynamics of the vehicle is transformed to the error one. Partial state-feedback linearization, backstepping and non-linear damping techniques are utilized to stabilize the above system and force the tracking error to a neighborhood about zero that can be made arbitrarily small. Simulation results that validate the proposed tracking methodology are presented and discussed.

متن کاملRobust Sliding Mode Controller for Trajectory Tracking and Attitude Control of a Nonholonomic Spherical Mobile Robot
Based on dynamic modeling, robust trajectory tracking control of attitude and position of a spherical mobile robot is proposed. In this paper, the spherical robot is composed of a spherical shell and three independent rotors which act as the inner driver mechanism. Owing to rolling without slipping assumption, the robot is subjected to two nonholonomic constraints. The state space representatio...

In this paper, a dual system consisting of two 5 DOF (RRRRR) robot manipulators is considered as a cooperative robotic system used to manipulate a rigid payload on a desired trajectory between two desired initial and end positions/orientations. The forward and inverse kinematic problems are first solved for the dual arm system. Then, dynamics of the system and the relations between forces/momen...
متن کاملAdaptive Robust Control for Trajectory Tracking of Autonomous underwater Vehicles on Horizontal Plane
This manuscript addresses trajectory tracking problem of autonomous underwater vehicles (AUVs) on the horizontal plane. Adaptive sliding mode control is employed in order to achieve a robust behavior against some uncertainty and ocean current disturbances, assuming that disturbance and its derivative are bounded by unknown boundary levels. The proposed approach is based on a dual layer adaptive...
