Back-Stepping Adaptive Attitude Control of Over-Actuated Spacecraft

Abstract

A novel robust adaptive back-stepping control scheme for attitude maneuver of over-actuated spacecraft system with redundant reaction fly-wheels (RWs) is proposed. The robust adaptive controller based on back-stepping may achieve the high accuracy and speed of the attitude control for the rigid spacecraft with uncertain inertia matrix and bounded external disturbs. The Lyapunov functions are employed to analyze and prove the systems stability, so the fine and accuracy performances are ensured. The numerical simulation results verify the effectiveness and feasibility of the control schemes derived here using the MATLAB/SIMULINK software.
