| 摘 要： | 针对三维空间内的高速飞行目标,提出了一种可用于固体动能拦截器助推段的精确最优控制方法。考虑了地球非球形摄动的影响,建立了有限推力拦截器最优控制问题动力学模型,并用直接配置法与SQP方法进行了数值求解,得到了更加精确的助推段控制方案。算例证明该方法有效。

| Abstract: | Aiming at the high speed flight targets in three-dimensional space,an accurate optimal control method for solid propellant interceptor in boost stage was put forward.Considering oblateness of the earth,the kinetics model of optimal control problem of limit thrust interceptor was derived.The problem was solved numerically by means of the direct collocation method and SQP.A more accurate optimal control scheme for the boost stage was obtained.The effectiveness of the method is verified by the example. |
