A guidance control method is proposed for the mission of autonomous rendezvous and docking with non-cooperative target spacecraft. Firstly, the relative motion equations of state are described in a line of sight coordinate frame. Then artificial potential function guidance is used for chaser to approach non-cooperative target. Moreover, this guidance method is based on fuzzy logic system which satisfies...
A guidance control method is proposed for the mission of autonomous rendezvous and docking with non-cooperative target spacecraft. Firstly, the relative motion equations of state are described in a line of sight coordinate frame. Then artificial potential function guidance based-fuzzy logic system, which adapts the parameters of the potential function, is used for chaser to approach non-cooperative...
Mass property of space vehicle changes apparently during and after mating and cannot be predicted or measured at times, yet it needs to be accurately known for mated flight control or attitude control and momentum management. A discrete Kalman Filter (KF) based estimation method is developed, measurements of single point acceleration, angular velocity and angular acceleration are employed to extract...
The two coplanar elliptic-to-elliptic orbits transfer with two-impulse is considered in this paper. The problem is the rendezvous of two spacecrafts, and the target spacecraft is not fixed in its orbit, but keep moving as same as the tracing spacecraft. To solve the problem, the transfer time is computed using Lambertpsilas theorem and iterative algorithm. And improved genetic algorithm is also used...
