Abstract

This paper investigates a fuzzy-logic-based integrated orbit-attitude-vibration prescribed-time controller for large-scale flexible spacecraft to achieve the high-precision orbit-attitude-vibration stabilization. Due to the existence of nonlinear coupling effects, a refined T-S fuzzy model based on the orbit-attitude-vibration dynamics of large-scale flexible spacecraft is constructed to represent the nonlinear characteristics and avoid the calculation singularity. Then, a prescribed-time controller is designed to stabilize the closed-loop system within a prescribed time with precise convergence rate where Lyapunov stability analysis is performed to prove the prescribed-time stability. Simulation results shows the effectiveness of the proposed control strategy.
