Abstract :
The LEO(Low-Earth-Orbit) drag-free satellite provides low-interference test environment for the validation of relativity, detection of gravitational waves and measurement of gravity field, which offset all kinds of disturbances from the space by continuous active control to achieve a state of pure free falling. One of the important researches is to ensure the control accuracy and performance. In this paper, we will study the finite-time control problem for the drag-free system with stochastic disturbance, and ensure the stochastic system catches stabilization in finite time. The simulation result indicate the effectiveness of the proposed controllers.
