摘　　要：针对高超声速飞行器飞行高度和飞行马赫数变化范围大,其数学模型具有严重非线性、不稳定性、多变量耦合以及不确定的空气动力学参数等特点,提出了动态面控制方法为其设计飞行控制系统。该方法通过构造动态面变量并根据能达条件,来设计中间的虚拟控制信号和最终的控制信号。通过在控制律设计过程中增加一阶动态滤波器,避免了设计过程中对非线性虚拟控制信号的微分,大大减少了控制律的计算量。并以某常规高超声速飞行器纵向模型为对象进行仿真。仿真研究表明该控制方法较好的实现了高超声速飞行器对指令信号的跟踪。For the feature that a hypersonic vehicle has a large span of flight height and flight Mach number, and complicated flight environment, the model of which is highly nonlinear, unstable, multivariable coupled and includes uncertain aerodynamic parameters, dynamic surface control method is proposed to design its flight control system. The virtual signal and final control signal are designed by constructing dynamic surface variables and reachable conditions. The method does not involve differentials of some nonlinear signals by adding first order dynamic filters, and the calculation of control law is decreased greatly. The simulation on a generic hypersonic vehicle demonstrates that the proposed method can track the flight commands well.
