摘　　要：传统的三通道(俯仰、偏航、滚转)独立小扰动导弹模型不能适应在大攻角与大过载下的控制,于是文中提出基于非线性块对角控制来解决。首先着重分析导弹的垂直转弯飞行方案,鉴于导弹的四层结构并非仿射型,然后对所建立的分层块对角模型进行仿射处理,并采用推力矢量控制方法实现了导弹垂直转弯的块对角控制器设计。最后在模型精准和气动参数摄动下,进行了数字仿真,结果表明系统在完成垂直转弯的同时,还具有很强的鲁棒性。Independent small disturbed missile model of traditional sile control in big attack angle and over loading, so the nonlinear three channels （pitching, yawing and rolling） can＇t adapt to misblock diagonal control was proposed to solve it. Firstly, the missile flight scheme of vertical turn was analyzed, considering the four layers of block diagonal model not to be affine. Secondly, the layered model was affinily processed, and a nonlinear block diagonal controller design based on missile turning trajectory in the way of reaction-jet control was achieve. In the end, in veracious model and pneumatic parameter diversifying, some mathematic simula- tions were conducted, which show vertical turn can be achieved by the method with good robustness.
