Self-organising satellite constellation in geostationary Earth orbit [PDF]

open access: yes, 2015
This paper presents a novel solution to the problem of autonomous task allocation for a self-organizing satellite constellation in Earth orbit. The method allows satellites to cluster themselves above targets on the Earth’s surface.

Global path guided vehicle obstacle avoidance path planning with artificial potential field method

open access: yesIET Cyber-systems and Robotics, 2023
An artificial potential field method based on global path guidance (G‐APF) is proposed for target unreachability and local minima problems of the conventional artificial potential field (APF) method in complex environments with dynamic obstacles.

Robot Local Path Planning Based on Improved Artificial Potential Field Method [PDF]

open access: yesJisuanji gongcheng
This study proposes an improved Artificial Potential Field (APF) algorithm (called FC-V-APF) based on Fuzzy Control (FC) and a virtual target point method to solve the local minimum trap and path redundancy issues of the APF method in robot local path ...

Solving the potential field local minimum problem using internal agent states [PDF]

open access: yes, 2008
We propose a new, extended artificial potential field method, which uses dynamic internal agent states. The internal states are modelled as a dynamical system of coupled first order differential equations that manipulate the potential field in which the ...

Path Planning Method With Improved Artificial Potential Field—A Reinforcement Learning Perspective

open access: yesIEEE Access, 2020
The artificial potential field approach is an efficient path planning method. However, to deal with the local-stable-point problem in complex environments, it needs to modify the potential field and increases the complexity of the algorithm.

Research on path planning of multi-rotor UAV based on improved artificial potential field method [PDF]

open access: yesMATEC Web of Conferences, 2021
UAV needs sensor to fly in an environment with obstacles. However, UAV may not be able to move forward when it encounters a large obstacle, or UAV will be in a dangerous state when the sensor fails briefly which disturbed by the environment factors.

Automatic collision avoidance of ships [PDF]

open access: yes, 2008
One of the key elements in automatic simulation of ship manoeuvring in confined waterways is route finding and collision avoidance. This paper presents a new practical method of automatic trajectory planning and collision avoidance based on an artificial

Critical point network for drainage between rough surfaces [PDF]

open access: yes, 2007
In this paper, we present a network method for computing two-phase flows between two rough surfaces with significant contact areas. Low-capillary number drainage is investigated here since one-phase flows have been previously investigated in other ...
