Robust Trajectory Tracking in Satellite Time-Varying Formation Flying

IEEE Transactions on Cybernetics, 2021
The robust time-varying formation control problem for a group of satellites is addressed. By the static state feedback control strategy and the disturbance estimation theory, a formation flying controller is proposed for the satellite group to form desired time-varying formation patterns and trajectories, and achieve the satellite attitude consensus ...

Formation Flying Satellites: Control By an Astrodynamicist

Celestial Mechanics and Dynamical Astronomy, 2001
Potential periodic formation orbits can be identified using Hill's equation. However, as gravitational perturbations destroy the periodicity, a control is required to maintain the desired orbits. Here, the authors address the control of individual satellites as well as the control of the whole constellation.

Satellite Formation Flying Maneuver Control

Mekhatronika, Avtomatizatsiya, Upravlenie, 2019
A problem of a formation flying satellites maneuver control is presented. Among the most important criteria for satellite formation flying control system are active period maximization, precision of the configuration, secure motion (without collisions of satellites).

Formation Flying Control of Small Satellites

AIAA Guidance, Navigation, and Control Conference, 2010
A new second order sliding mode (2nd-SM) control algorithm of MIMO nonlinear systems for low thrust multiple picosatellites formation flying is proposed in this paper. The problem is tackled by applying chatteringfree 2nd-SM control law as a control scheme for the case where the leader satellite is in circular and elliptical reference orbits under J2 ...

Satellite formation flying via lyapunov stabilization

2007 International Conference on Control, Automation and Systems, 2007
This paper presents a control scheme for satellite formation flying based on Lyapunov stabilization. It is assumed that the angular rate and angular acceleration of true anomaly are not known, but they are bounded. In such a case, the control law proposed in this paper guarantees asymptotical convergence of the states to the desired values.

Satellite Formation Flying Design and Evolution

Journal of Spacecraft and Rockets, 2001
Several satellite formation e ying designs and their evolution through time are investigated. Satellite formation e ying designs arederived from the linearized equations of relative motion under two-body dynamics better known as Hill’ s equations (Hill, G. W., “ Researches in the Lunar Theory,”American Journal of Mathematics , Vol. 1, No.

Adaptive LQR for Satellite Formation Flying

2021
As shown in Chapter 3, a linearized relative dynamics based LQR control theory does not lead to satisfactory results when the formation is desired in an elliptic orbit and/or when the relative separation is high. It was also demonstrated in Chapter 6 that the SDRE approach is a relatively better to address such issues to a reasonable extent ...

Optimal Reconfiguration of Formation Flying Satellites

Proceedings of the 44th IEEE Conference on Decision and Control, 2006
We employ a recently developed new technique for the numerical treatment of optimal control problems for mechanical systems in order to compute optimal open loop control laws for the reconfiguration of a group of formation flying satellites. The method is based on a direct discretization of a variational formulation of the dynamical constraints.

Ultra-Dense LEO Satellite Based Formation Flying

IEEE Transactions on Communications, 2021
In this article, we consider a downlink ultra-dense LEO-based multi-terminal satellite system where multiple satellites fly in formation to serve a number of ground terminal stations for data transmission. Benefited from the dense satellite constellation, high channel capacity can be achieved via the massive virtual antenna array formed by multiple ...

μ Control for Satellites Formation Flying

Journal of Aerospace Engineering, 2007
In this paper, a μ controller is designed for a satellite formation flying system around the Earth based on an uncertainty model derived from a nonlinear relative position equation. In this model, nonzero eccentricity and varying semimajor axis are included as parametric uncertainties.
