【摘要】 针对高超声速飞行器纵向模型的快时变、强耦合和高度非线性的特点,在考虑模型不确定性的情况下,采用李导数的方法对某型高超声速飞行器进行输入输出的精确线性化。基于线性化后的模型,提出一种非线性动态逆控制的方法,并对其稳定性进行分析,实现对该型高超声速飞行器的轨迹跟踪控制。并利用Matlab搭建仿真平台,仿真结果显示仿真平台的正确性和控制算法的有效性。更多还原

【Abstract】 Aiming at the significant feature that the hypersonic aircraft is fast time-varying,strong coupling and highly nonlinear,Lie derivative was adopted for Input-Output linearization to a hypersonic aircraft with uncertainties.Based on the linearized model,a dynamic inversion tracking controller was proposed,and stability analysis was given.Then a simulation platform was built based on Matlab.Simulation results show the correctness of the simulation platform and the effectiveness of the control approach.更多还原
