防空导弹弹道跟踪制导规律研究

A guidance law for air defence missile trajectory tracking

根据李亚普诺夫稳定性原理,利用基准优化弹道参数构造滑动面,提出了一种新的弹道跟踪制导规律。对跟踪制导规律的数学原理进行了描述,给出了详细的推导过程和二维平面弹道仿真数学模型及仿真结果。结果表明所提出的弹道跟踪制导规律能使导弹快速跟踪基准优化弹道。

Based on the Lyapunov stability theory,a sliding surface is structrued by using nominal optimal trajectory parametersA new guidance law of the trajectory tracking is proposed The mathematic theorem and the derivation procedure of the guidance law are given in detailThe digital computer trajectory simulation of twodimensional missile guidance problem is performed The results demonstrate that the proposed guidance law of the trajectory tracking can make the missile tracking nominal optimal trajectory fast
