Optimal Formation Reconfiguration Using Genetic Algorithms

2009 International Conference on Computer Modeling and Simulation, 2009
Spacecraft formation flying has received an enormous amount of attention over the past few years, researcher have begun to consider the advantages of spacecraft formation compared to large, complex, single purpose spacecrafts, the use of spacecraft formation has the potential to expand functionality, distribute risk and reduce cost and also it involves

A Time-Fuel optimal for spacecraft formation reconfiguration

2007 IEEE Congress on Evolutionary Computation, 2007
In this paper, trajectory planning for spacecraft formation reconfiguration is modeled as a MOP (multi-objective optimisation problem) and a niched evolutionary algorithm is proposed. With a problem specific real-valued representation of candidate solutions and evolutionary operators, the algorithm could find the time-fuel front of this problem and ...

Teleoperated mobile robot groups with reconfigurable formation

2014 IEEE International Conference on Autonomous Robot Systems and Competitions (ICARSC), 2014
In this paper a formation control algorithm is proposed for teleoperated mobile robot groups. A leader robot is teleoperated directly by the human operator using a primary haptic device. The rest of the mobile robots follow the virtual reference structure attached to the leader.

Decentralized and dynamic group formation of reconfigurable agents

Memetic Computing, 2014
Adaptive group formation in dynamic environments performed by heterogeneous swarms of simple agents is an interesting research topic. In this paper we consider an unsupervised scenario where the individuals of the swarm have limited information about their environment as well as limited communication capabilities.

Energy and time efficient formation reconfiguration strategies

Proceedings of the 48h IEEE Conference on Decision and Control (CDC) held jointly with 2009 28th Chinese Control Conference, 2009
Energy-efficient and time-efficient reconfiguration strategies for formation flying of autonomous agents are presented. It is assumed that a finite set of possible formations is given, and that the probability of each formation in this set is known a priori. The idea is to move the agents to floating stations in the idle time, i.e. the time between the

An adaptive reconfigurable formation flight control design

Proceedings of the 2003 American Control Conference, 2003., 2004
In this paper we derive adaptive reconfigurable formation control algorithms using a leader-follower framework in the presence of loss-of-effectiveness control effector failures in the follower vehicle. We first present stable formation control algorithms designed to maintain the relative distances between the vehicles close to their desired values.

Reconfiguration of a vehicle formation with ring communication structure

2016 European Control Conference (ECC), 2016
In multiple vehicle formations, there is often a need to reconfigure communication graphs to accommodate (1) for addition or removal of vehicles or (2) for change in positions of the vehicles within a given formation. This problem is commonly referred to as the topology or graph reconfiguration problem.

Minimization and equalization of energy for formation flying reconfiguration

IEEE International Conference on Robotics and Automation, 2004. Proceedings. ICRA '04. 2004, 2004
An efficient method for the generation of collision free, energy optimal, reconfiguration trajectories with energy equalization constraints of formation flying is presented. The main idea is to introduce a set of way-points through which the spacecraft are required to pass combined with certain parameterizations of the trajectories.

Cell formation in the presence of reconfigurable machines

The International Journal of Advanced Manufacturing Technology, 2006
In this research, an approach is made to design machine cells using modular machines to achieve certain characteristics of reconfigurable manufacturing. Each machine considered in the model consists of some basic and auxiliary machine modules. By changing the auxiliary modules, different operations can be performed on the machines. A similarity measure
