3D Formation Control of Autonomous Vehicles Based on Null-Space
(Springer, 2016-12)
This paper proposes a new algorithm for controlling a formation of multiple autonomous aerial vehicles based on multiple control objectives. The strategy includes using the null space of a Jacobian matrix to achieve the ...
RETROGRADE AND DIRECT POWERED AERO-GRAVITY-ASSIST TRAJECTORIES AROUND MARS
(Univ Nacional Autonoma Mexico, Inst De Astronomia, 2018-04-01)
A Gravity-Assist maneuver is used to reduce fuel consumption and/or trip times in interplanetary missions. It is based in a close approach of a spacecraft to a celestial body. Missions like Voyager and Ulysses used this ...
STUDYING DIRECT AND INDIRECT EFFECTS OF IMPULSES IN POWERED AERO-GRAVITY-ASSIST MANEUVERS AROUND VENUS
(Univ Nacional Autonoma Mexico, Inst De Astronomia, 2018-10-01)
The study of aero-gravity-assisted maneuvers around Venus is the focus of the present paper. These are maneuvers that combine the passage by the gravity field of the planet with an impulsive maneuver that is applied at the ...
Dynamics around an asteroid modeled as a mass tripole
(2020-01-01)
The orbital dynamics of a spacecraft orbiting around irregular small celestial bodies is a challenging problem. Difficulties to model the gravity field of these bodies arise from the poor knowledge of the exact shape as ...

Cyclic interconnection for formation control of 1-D vehicle strings
(2016)
In this paper, we study a formation control scheme for a 1-D string of vehicles. Each member tracks the movement of its immediate predecessor but also the first vehicle tracks the position of the last member of the string. ...
Local and global path generation for autonomous vehicles using splines
Context: Before autonomous vehicles being a reality in daily situations, outstanding issues regarding
the techniques of autonomous mobility must be solved. Hence, relevant aspects of a path planning for
terrestrial ...
