Based on non-affine models of hypersonic space vehicles, the tracking control problem of hypersonic vehicles is studied and analyzed in this article using funnel robust model-free control mechanism considering parametric uncertainty and external disturbances. First, the control system is decomposed into altitude subsystem and velocity subsystem. For altitude subsystem, we propose a concise funnel robust model-free control mechanism based on error driving, and a novel model transformation approach is applied to the controller design. The new model-free controller only contains a Hurwitz stable term and a filtering term, and does not need precise motion model and too much calculation, so it can improve the calculation speed of the system. For velocity subsystem, only a concise proportional-integral controller is needed to meet the tracking requirements. Moreover, the devised controller is capable of guaranteeing funnel performance on the altitude and velocity tracking errors. Finally, numerical simulation results are presented to verify the efficiency of the design.

本文基于高超声速空间飞行器的非仿射模型，采用考虑参数不确定性和外部干扰的漏斗鲁棒无模型控制机制，研究和分析了高超声速飞行器的跟踪控制问题。首先，控制系统分解为高度子系统和速度子系统。对于高度子系统，我们提出了一种基于误差驱动的简洁漏斗鲁棒无模型控制机制，并将一种新颖的模型转换方法应用于控制器设计。新的无模型控制器只包含一个Hurwitz稳定项和一个滤波项，不需要精确的运动模型和过多的计算，可以提高系统的计算速度。对于速度子系统，只需要一个简洁的比例积分控制器就可以满足跟踪要求。此外，所设计的控制器能够保证漏斗在高度和速度跟踪误差方面的性能。最后通过数值模拟结果验证了设计的有效性。
