Moving-Mass Attitude Control of Hypersonic Vehicle Based on Fuzzy Tree

Abstract

In this paper, Newton-Euler method is proposed to model the dynamic model for the moving-mass attitude of hypersonic vehicle and a coupled nonlinear system is obtained by reasonable simplification. A fuzzy tree inversion model is established to realize the decoupling and linearization of the three channels. For nonlinear system inversion error caused by modeling error and uncertainty, a closed-loop controller for each linear subsystem is designed to track attitude angle. Finally, the simulation results show that the control method is effective.
