Feature Point Tracking for Incomplete Trajectories

Computing, 1999
A new algorithm is presented for feature point based motion tracking in long image sequences. Dynamic scenes with multiple, independently moving objects are considered in which feature points may temporarily disappear, enter and leave the view field. This situation is typical for surveillance and scene monitoring applications.

State tracking through optimized trajectory tracking

Proceedings of the 1999 American Control Conference (Cat. No. 99CH36251), 1999
A new computational method is presented for solution of the noncausal optimal tracking problem for discrete time systems. The method may be used for both linear systems (LQ tracking) and nonlinear systems. Solution of the problem may be obtained with a simple recurrent algorithm which is derived from an optimization procedure.

Neural network trajectory tracking of tracked mobile robot

2019 16th International Multi-Conference on Systems, Signals & Devices (SSD), 2019
In this paper, an online neural network trajectory tracking controller for a tracked mobile robot is proposed. The mobile robot used in this study has only three binary sensors to obtain its position/error from the target trajectory. Due to poor binary sensors which return only 0 or 1, it is impossible to get accurate position/error.

Trajectory planning of tracked vehicles

[1993] Proceedings IEEE International Conference on Robotics and Automation, 2002
The motions of planar tracked vehicles are governed by three force and moment equations. The force equation perpendicular to the tracks represents a dynamic nonholonomic constraint which is explicitly dependent on vehicle speed. It couples path planning with trajectory planning.

Optimal trajectory tracking

2016
This thesis investigates optimal trajectory tracking of nonlinear dynamical systems with affine controls. The control task is to enforce the system state to follow a prescribed desired trajectory as closely as possible. The concept of so-called exactly realizable trajectories is proposed.

Trajectory Tracking of Multibody Spacecraft

Dynamic Systems and Control, 1996
Abstract This paper addresses the problem of trajectory tracking of multibody spacecraft. The class of systems considered consists of a central body to which a number of articulated appendages are attached. Each appendage itself could be a serial chain of bodies.

Trajectory tracking for a helicopter model

The Aeronautical Journal, 2001
AbstractIn this paper an algorithm for the trajectory tracking of a three-dimensional trajectory, assigned as a function of time, is presented. The proposed control system is suitable for application on unmanned aerial vehicles (UAVs) or for aircraft that require accurate path tracking, as in the case of rotorcraft in nap-of-the-earth (NOE) flight ...

Tracking control for UAV trajectory

Proceedings of 2014 IEEE Chinese Guidance, Navigation and Control Conference, 2014
An online UAV collision avoidance trajectory planning algorithm based on Pythagorean Hodograph (PH) curve is presented. To fully use the PH trajectories performance that the curvature of the curve is continuous and precisely known, the backstepping trajectory tracking control is introduced.

Trajectory Tracking Feedback Control

2016
This chapter is dedicated to the trajectory tracking control of a large class of frictionless Lagrangian systems with multiple unilateral constraints, complementarity conditions and impacts: rigid-joint rigid-body systems and flexible-joint rigid-body systems.

Multi-rotor robust trajectory tracking

2015 23rd Mediterranean Conference on Control and Automation (MED), 2015
This paper develops a position control strategy of a multi-rotor system, which moves from an X-Y way-point to another at constant maximum-achievable velocity, and follows rectilinear trajectories between way-points with slight deviations during transients.
