含扩张状态观测器的高超声速飞行器动态面姿态控制

针对高超声速飞行器复杂非线性、高不确定性和强通道耦合等特点，提出了一种飞行器姿态控制的非线性设计方法。根据高超声速飞行器无动力飞行的姿态运动方程组，给出一个可面向姿态控制的非线性设计模型。针对一类非线性系统，提出了一种基于扩张状态观测器（ESO）的动态逆设计方法，并通过动态面控制理论，将其应用于高超声速飞行器的三通道姿态控制中。仿真结果表明，相比基于传统动态逆的动态面控制方案，本文所提出的控制方案可以保证飞行器快速、精确地跟踪角位置指令，并且具备针对系统不确定性的强鲁棒性能。

Dynamic Surface Attitude Control for Hypersonic Vehicle Containing Extended State Observer

Aiming at the complicated nonlinearities, high uncertainties and strong couplings of hypersonic vehicle, a nonlinear attitude control method is put forward. According to the attitude motion equations of unpowered hypersonic vehicle, a nonlinear design model for the attitude control is established. With regard to a class of nonlinear system, a dynamic inversion control (DIC) based on extended state observer (ESO) is proposed and then applied to the attitude control of hypersonic vehicle by using dynamic surface control (DSC) approach. Simulation results show that, the chosen vehicle designed by using the proposed control scheme can track the angle position commands more quickly and accurately, compared with the other DSC scheme based on traditional DIC. Furthermore, it also possesses stronger robustness against system uncertainties.
