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。
Aiming at the characteristics of hypersonic gliding aircraft, such as fast changing parameters, high uncertainty and strong channel coupling, a nonlinear design method of attitude control is studied. According to the motion model of non-motive force flight, a non-linear design model of attitude-oriented control is established. A dynamic inverse control scheme with robust performance is proposed. The dynamic plane control method is applied to the attitude control of gliding aircraft. The simulation results show that compared with the traditional control scheme based on dynamic inverse, the proposed scheme can ensure that the gliding aircraft can track the command quickly and accurately and has strong robustness against the system uncertainty.
