研究了高超声速飞行器在存在不确定性和外部干扰情况下的跟踪控制问题。针对飞行过程中不确定性和干扰的精确界通常未知的问题，提出了一种基于干扰观测器（DOB）的自适应高阶滑模控制方法。为了在保持较强鲁棒性的同时减轻抖振影响，将DOB和增益自适应相结合的方法引入HOSMC。DOB用于估计和抑制不确定性和外部干扰。此外，自适应控制律的开发，以补偿估计误差。通过结合DOB和自适应HOSMC，不必要的大增益保持鲁棒性减少，因此，抖动减轻。仿真结果表明，该控制方法在不确定性和外部干扰下具有较强的鲁棒性和良好的跟踪性能，并有效地抑制了抖振。
In this study, hypersonic vehicle (HV) tracking control in the presence of uncertainties and external disturbance is investigated. As the exact bounds of uncertainties and disturbances are usually unknown during flight, a disturbance observer (DOB)-based gain adaptation high-order sliding mode control (HOSMC) method is proposed for HVs. To mitigate the chattering effect while maintaining strong robustness, a method combining the advantages of the DOB and gain adaptation is introduced into the HOSMC. The DOB is employed to estimate and reject the uncertainties and external disturbance. Additionally, an adaptive control law is developed to compensate for estimation errors. By combining the DOB and the adaptive HOSMC, the unnecessarily large gain for maintaining robustness is reduced; thus, the chattering is mitigated. The effectiveness of the proposed control method is validated via simulation, in which a strong robustness, high tracking performance, and reduced chattering effect are achieved under uncertainties and external disturbance.
