Abstract :
This study investigates the problem of finite-time attitude stabilisation in probability for a class of stochastic spacecraft systems. Based on the stochastic finite-time stability theorem, a continuous control law is proposed to guarantee the solution of the closed-loop system will converge to the origin in finite time and stay at the origin thereafter with probability one. A simulation example is given to illustrate the effectiveness of the proposed method.
