一种高超声速飞行器自抗扰控制方法
By designing a novel extended state observer with a switching function between linear and nonlinear functions, the problems of single observer and coarse estimation in the active disturbance rejection control of hypersonic vehicles are solved. This enables targeted estimation and compensation of disturbances, thereby enhancing the robustness and anti-interference capability of the control system.

Abstract
本发明公开了一种高超声速飞行器自抗扰控制方法。本发明中，提出了新的线性与非线性切换函数，并基此设计了速度和高度子系统的扩张状态观测器。特别地，对于高度子系统的不匹配干扰，将其当作单独状态来估计。另外，在设计控制律时将系统干扰值融入，达到对其进行补偿的目的。理论推导和结果验证表明，所设计的控制策略充分利用了线性与非线性状态观测器的优点，能有效地抑制不确定性对控制系统的影响，增强了控制系统的鲁棒性。本发明面向工程实际问题，成果将为高超声速飞行器高性能控制提供参考，具有重要的应用价值。
