摘要
针对高超声速滑翔飞行器参数变化快、不确定性高、通道耦合强的特点,研究了一种姿态控制的非线性设计方法。根据无动力飞行姿态运动模型,建立了可面向姿态控制的非线性设计模型。提出了一种具有鲁棒性能的动态逆控制方案,并通过动态面控制方法,将其应用于滑翔飞行器的姿态控制中。仿真结果表明,相比基于传统动态逆的控制方案,所提出的方案可以保证滑翔飞行器快速、精确地跟踪指令,并且具备针对系统不确定性的强鲁棒性能。
Regarding the fast parameter variations, high uncertainties and strong couplings of hypersonic gliding vehicle （HGV） , a nonlinear attitude control method is proposed for HGV. According to the attitude motion model of unpowered HGV, a nonlinear model oriented to attitude controller design is established. A dynamic inversion control （ DIC ） with robust property is proposed and then applied to the HGV attitude control by using dynamic surface control （DSC） approach. The simulation results show that the chosen vehicle using the proposed control scheme can track the commands more rapidly and accurately by comparing to other control scheme based on traditional DIC. Furthermore, it also possesses stronger robustness against system uncertainties.
