This paper introduces a decentralized design technique for satellite formation using algebraic graph theories. Each satellite controls itself using the relative states describing its position and velocity relative to neighboring satellites it can sense. The formation control problem with n satellites is thus reduced into stabilization problem of single satellite with the identical relative dynamics,...
Passive and periodic formations minimize the active control of long-term satellite formation flying. Among different passive and periodic formations, the circular-like ones have potential applications in many formation flying missions. This paper shows that such formations under J2 perturbation are only possible at the critical inclination. It is revealed that strict constraints for both the reference...
Orbit at the critical inclination is a practical option for long-term satellite formations flying around an oblate Earth. This paper establishes that passive and periodic relative orbits with cross-track motion are only possible at the critical inclination under conditions that all satellites share the same inclination, the same semi-major axis and the same eccentricity. Furthermore, a quasi-periodic...
Formation design considering the eccentricity and the J2 perturbation is significant for a practical satellite formation flying mission. The linear solution of satellite relative motion proves that, by setting all satellites having the same mean orbit elements of semi-major axis, eccentricity, inclination and right ascension of ascending node, a passive in-plane formation is periodic and stable in...
In this paper, we focus on the design of fuel-optimal satellite formation keeping strategy using a low thrust propulsion system. The proposed controller includes feedback control and feedforward control. For feedback control, a real-time fuel-optimal control approach is proposed. The fuel-optimal control problem is then converted into a quadratic programming problem by application of a Legendre pseudospectral...
Numerous controllers have been proposed based on linear Hill's equations for satellite formation control. To date, most of these controllers assumed that the system model is well defined, and all the states are known. In this paper, robust constrained model predictive controllers are designed which allows explicit incorporating of the description of parametric uncertainty and the actuator magnitude...
Numerous controllers have been proposed based on linear Hill's equations for satellite formation control. To date, most of these controllers assumed that the system model is well defined, and the disturbances are small. Previous studies have failed to consider the problem of disturbance rejection. In this paper, Hinfin controllers are designed for disturbance attenuation based on linear Hill's equations...
The content of this paper is a subtask of Nation-863 High Tech Item. Two micro-satellites perform formation-flying and inter-satellites communication demonstration test in a circular orbit. The optimizing design method of space circular formation order based on mend heredity algorithmic is given; the method can ensure formation order steadily for a long time under various absorb impetus. The inter-satellite...
