摘　　要：针对飞行器大角度机动的控制问题具有强耦合、高度非线性、参数不确定性等特点,本文首先利用逆动态控制的非线性解耦能力对系统进行非线性解耦,然后基于变结构控制的鲁棒性进行控制器的设计,并在MATLAB环境下进行了仿真研究。仿真结果表明,该控制方法在有外界干扰和系统参数不确定的条件下具有较快的收敛性和一定的鲁棒性。As the large-angle maneuver control of aircraft has characteristics of strong decoupling, high nonlinear, parameter uncertainty and so on. Firstly, the system is decoupled nonlinearly by using the inverse dynamic control, which has the ability of nonlinear decoupling. Then, the controller is designed based on the robustness of the variable structure control. Furthermore, a simulation is carried out by using MATLAB. The simulation results show that the control method has fast convergence and robustness, which is under conditions of exterior disturbances and uncertainty of system parameters.
