摘要： 针对含有时变不确定参数的高超声速飞行器模型，提出了一种新颖的鲁棒变增益跟踪控制方法.该方法可以解决传统固定增益鲁棒控制器难以处理时变大摄动的难题，进而提高高超声速飞行器的鲁棒性和抗干扰能力.跟踪控制器设计条件在鲁棒优化技术框架中给出，同时控制器增益按照所设计的切换律而变化.所提出的设计方法在保证高超声速飞行器鲁棒稳定性的同时，也实现了飞行器对指令信号的跟踪.最后，针对高超声速飞行器的仿真结果进一步验证了方法的有效性.

Abstract: A novel robust tracking control design method was proposed for hypersonic vehicles with timevarying uncertainties. Compared with traditional robust controller with fixed gains， the method presented had better capability to deal with large timevarying parameter perturbation and enhance the robustness of hypersonic vehicles. Sufficient conditions for controller design were given in the framework of robust optimization technique， and the controller gains was online adjusted based on the designed switchinglaws. The proposed robust tracking controller could not only guarantee the stability of hypersonic vehicles， but also track the command signals about height and speed quickly， even in the case of external disturbance existing. Some numerical simulations demonstrated the validity of this new robust control method.

Key words: hypersonic vehicle, timevarying uncertainty, controller with variable gains, tracking control, robust control
