A path following algorithm for the graph matching problem [PDF]

, 2008
We propose a convex-concave programming approach for the labeled weighted graph matching problem. The convex-concave programming formulation is obtained by rewriting the weighted graph matching problem as a least-square problem on the set of permutation ...

A Path Algorithm for Constrained Estimation [PDF]

, 2011
Many least squares problems involve affine equality and inequality constraints. Although there are variety of methods for solving such problems, most statisticians find constrained estimation challenging.

3DOF Adaptive Line-Of-Sight Based Proportional Guidance Law for Path Following of AUV in the Presence of Ocean Currents

Applied Sciences, 2019
In order to achieve high-precision path following of autonomous underwater vehicle (AUV) in the horizontal plane, a three degrees-of-freedom adaptive line-of-sight based proportional (3DOFAPLOS) guidance law is proposed.

Improving Tracking of Trajectories through Tracking Rate Regulation: Application to UAVs

Sensors, 2022
The tracking problem (that is, how to follow a previously memorized path) is one of the most important problems in mobile robots. Several methods can be formulated depending on the way the robot state is related to the path.

Recommending Paths: Follow or Not Follow?

IEEE INFOCOM 2019 - IEEE Conference on Computer Communications, 2019
Mobile social network applications constitute an important platform for traffic information sharing, helping users collect and share sensor information about the driving conditions they experience on the traveled path in real time. In this paper we analyse the simple but fundamental model of a platform choosing between two paths: one with known ...

Internal Model Control-Based Observer for the Sideslip Angle of an Unmanned Surface Vehicle

Journal of Marine Science and Engineering, 2022
Since the sideslip angle is often ignored or simplified in the process of path following of unmanned surface vehicle by using the line-of-sight (LOS) guidance law because of its fast change and the difficulty of measurement, an observer was proposed by ...

Following 3D paths by a manipulator

Archives of Control Sciences, 2015
In the paper a description of a manipulator relative to a desired three-dimensional path was presented. The path is parameterized orthogonally to the Serret-Frenet frame which is moving along the curve.
