摘　　要：针对乘波体外形的高超声速飞行器存在的结构/推进/气动强耦合特性,利用鲁棒极点配置方法设计了自适应控制器,实现了对高超声速飞行器的速度和高度指令跟踪控制。基于弹性高超声速飞行器模型CSUAL-GHV,分别采用自适应鲁棒极点配置控制方法和自适应非鲁棒极点配置控制方法进行了数值仿真。结果表明,与非鲁棒极点配置控制方法相比,采用自适应鲁棒极点配置控制方法的控制系统不仅使飞行器能够很快地跟踪上速度和高度指令,跟踪误差小于1%,而且高超声速飞行器的弹性振动也得到了有效地抑制。This paper uses robust pole assignment method to design an adaptive velocity and altitude tracking control algorithm for the longitudinal model of a wave rider configuration air-breathing hypersonic vehicle,which has strong coupling between structure,propulsion and aerodynamics.Based on the elastic hypersonic vehicle model CSUALGHV,the simulations using adaptive robust pole assignment control method and adaptive non-robust pole assignment control method are carried out respectively.The results show that,compared with the non-robust pole assignment control method,control system using adaptive robust pole assignment control method not only achieves the velocity and altitude tracking goal with tracking error less than 1％,but also the vibration motion of the hypersonic vehicle is suppressed sufficiently.
