摘　　要：区别于传统低速飞行器,高超声速飞行器具有强非线性、快时变、强耦合及高度不确定性的动力学特征,对控制系统设计提出了很高的要求。针对高超声速飞行器纵向动力学模型,设计一种基于跟踪微分器的鲁棒反演控制器。把原理模型转化为仿射模型,基于动态逆和反演控制算法分别设计速度和高度控制器。将弹性模态转化为模型中的未知项,基于双曲正弦跟踪微分器对模型中的总不确定项进行估计,并在控制律中加以补偿。通过对比试验表明,引入双曲正弦跟踪微分器后能够有效提升控制系统的鲁棒性。Different from the traditional low-speed vehicle, hypersonic vehicle has the dynamic characteristics of strong nonlinearity, fast time-varying, strong coupling and high uncertainty, which puts forward high requirements for the design of control system.A robust back-stepping controller with hyperbolicsine-based tracking differentiator is designed for the longitudinal dynamics model of hypersonic flight vehicles. Firstly, the principle model is transformed to the affine form. Then, the velocity and altitude controller are developed based on dynamic inversion and back-stepping control method respectively. The elastic mode is transformed into the unknown term in the model. The total uncertainty in the model is estimated based on the hyperbolic sinusoidal tracking differentiator and compensated in the control law. The contrast simulation shows that the hyperbolic-sine-based tracking differentiator can improve the robust of controller effectively.
