Abstract:

Considering that the spacecraft flying along its fixed elliptical trajectory will easily be tracked and intercepted, a general approach based on jump control input is proposed for the spacecraft anti-tracking model-reference tracking control problem. By combing with the definition of stochastic stability and model-reference tracking, the mathematical description of the spacecraft anti-tracking model-reference tracking control problem is put forward. Based on both stochastic stability theory of jump systems and model reference tracking control method, a feedback controller with stochastic stability and a feedforward controller optimized with free parameters are built. The effectiveness of the proposed control scheme is illustrated by the numerical simulation result of spacecraft anti-tracking.
