Formation control with collision avoidance

IEEE Conference on Decision and Control and European Control Conference, 2011
We present a formation flight control strategy featuring a collision avoidance scheme. The control algorithm is based on a Sliding Mode controller. The controller sliding surfaces account for aircraft maneuvering limitations, restricting the required velocities to a feasible set.

Collision avoidance passive sonar

Proceedings of the Eighth ACM International Conference on Underwater Networks and Systems - WUWNet '13, 2013
Modems for underwater acoustic communications (acomms) have become nearly as much of a commodity technology as underwater releases or transponder systems. Modems today are at a similar stage as were mobile phones perhaps 15 years ago -- basic communications devices.

Distributed reactive collision avoidance

Autonomous Robots, 2012
The work contained in this paper concerns a novel approach to the n-vehicle collision avoidance problem. The vehicle model used here allows for three-dimensional movement and represents a wide range of vehicles. The algorithm works in conjunction with any desired controller to guarantee all vehicles remain free of collisions while attempting to follow ...

Generalized reciprocal collision avoidance

The International Journal of Robotics Research, 2015
Reciprocal collision avoidance has become a popular area of research over recent years. Approaches have been developed for a variety of dynamic systems ranging from single integrators to car-like, differential-drive, and arbitrary, linear equations of motion. In this paper, we present two contributions.

Collision avoidance for nonrigid objects

Zeitschrift für Operations Research, 1988
The path existence problem and the collision detection problem for time-varying objects in a geometric scene are discussed. For a large class of spherical nonrigid objects, exact solutions of the path existence problem are developed based on decomposition techniques and graph traversal.

Collision Avoidance Trajectory for an Ekranoplan

AIAA Atmospheric Flight Mechanics Conference, 2009
The risk of collision is one of the crucial aspects for the applications of Ekranoplans in civil transportation. In fact, the extremely low flight altitude of these aircraft increases dramatically the chances of interference between their flight path and the multitude of obstacles populating the surrounding area.

Collision avoidance dynamics for optimal impulsive collision avoidance maneuvers

2017 8th International Conference on Recent Advances in Space Technologies (RAST), 2017
This paper describes a method to calculate the optimal impulsive maneuver to avoid the collisions using Simplified General Perturbation 4 (SGP4) and Two Line Element (TLE). It also presents a rigorous analysis of the method to investigate the relative dynamics of the two colliding space objects assuming the encounter is instantaneous.

Modelling free flight with collision avoidance

Proceedings Seventh IEEE International Conference on Engineering of Complex Computer Systems, 2002
Free jlight has been proposed as a future alternative to the current policy in Air Trafic Management (ATM) where aircraft follow predefined corridors. In free Pight pilots can choose their own optimal routes, altitudes and velocities but are also responsible for the safe and fair resolution of trajectory conjlicts. This would require a safe distributed
