Characterization of Disturbances in the Space Environment for Autonomous Close-range Rendezvous of Cooperative Robots
نویسندگان
چکیده
The topic of autonomous close-range rendezvous is discussed in this paper. When designing a controller for an autonomous system, it is important to model the environment of the system as precisely as possible. This paper discusses the disturbances encountered in space and their effects on the rendezvous controller with particular focus on the effects in fuel usage and mission times. Simulations are performed for two scenarios: near circular low-Earth orbits and eccentric geosynchronous orbits. It was found that disturbances affected the controller for the eccentric geosynchronous orbits considerably more than that found for near circular lowEarth orbits, which largely can be attributed to aerodynamic drag experienced at periapsis.

Recently, data collection from seabed by means of underwater wireless sensor networks (UWSN) has attracted considerable attention. Autonomous underwater vehicles (AUVs) are increasingly used as UWSNs in underwater missions. Events and environmental parameters in underwater regions have a stochastic nature. The target area must be covered by sensors to observe and report events. A ‘topology cont...

متن کاملCooperative Control of Mobile Robots in Creating a Runway Platform for Quadrotor Landing
Multi-agent systems are systems in which several agents accomplish a mission in a cooperative manner. In this paper, a novel idea for the construction of a movable runway platform based on multi-agent systems is presented. It is assumed that an aerial agent (quadrotor) decides to make an emergency landing due to reasons such as a decrease in energy level or technical failure, while there is no ...
