| 摘 要： | 在空间拦截中，导弹产生饱和梯形波推力和三角形脉冲推力。用非线性精确线性化理论获得的制导律是连续制导律，它适用于导弹在大气层内飞行，不适于导弹在大气层外飞行。本文研究了非线性末制导律离散实现的解析法，用该方法获得的离散末制导律适用于导弹在大气层外飞行。

| Abstract: | In space interception,the missile produces saturation ladder type wave propulsion and trigonal pulse propulsion The guidance law gotten by nonlinear exact linearization is continuous guidance law,which is suited for the missile to fly in atmospher,but is not suited for the missile to fly in extra atmospher Analytic discretization of nonlinear guidance law is researched in the paper The discrete guidance law is suited for the missile to fly in extra atmospher |
