摘要

本文采用牛顿-欧拉法对高超声速飞行器的动质量姿态动力学模型进行建模，通过合理的简化得到一个耦合的非线性系统。建立了模糊树反演模型，实现了三通道的解耦和线性化。针对建模误差和不确定性引起的非线性系统反演误差，设计了各线性子系统的闭环控制器来跟踪姿态角。最后，仿真结果表明了该控制方法的有效性。

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

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.
