飞航导弹的地形跟踪控制器设计方法研究

根据奇异摄动理论,采用飞航导弹的分层控制方法,将地形跟踪控制系统分成速度、姿态角和角速度三部分,提出了一种利用动态逆滑模控制进行飞航导弹地形跟踪控制器的设计方法,同时充分考虑了导弹系统中的不确定性误差,保证了系统误差收敛。最后以飞航导弹非线性模型进行了6DOF仿真。从仿真结果可以看出,导弹能够准确跟踪地形轮廓飞行,表明所设计的地形跟踪控制器具有较强的鲁棒性和快速跟踪性。

Research on the TF Controller Design for Aerodynamic Missiles

Applying the theory of singular perturbations,this paper adopts an aerodynamic missile layered control algorithm to divide a terrain following system into the velocity layer,attitude angles layer and angular velocities layer.A dynamic inversion sliding mode control algorithm is proposed for the design of each layer controller to guarantee the tracking errors converge exponentially.Finally the results of one aerodynamic missile nonlinear six-degree-of-freedom simulation show that the missile can follow the terrain configuration accurately,and the designed controllers have own strong robustness and rapidly tracking ability.
