Dynamic programming algorithm was introduced to solve the problem. Based on discussion of calculation complexity and effectiveness, the exact DP Algorithm was successfully used in operative schedule of the collecting bucket in multi-car-single-layer mode, which has few service nodes. For problems with large number of service nodes, restricted DP algorithm was constructed to avoid rapid expand in calculation and memory demands during programming process. The restricted DP algorithm, successfully used in single-car-multilayer and compound service modes, gets balance between near optimal programming results and reasonable programming time, so as to meet the real time schedule demands.

文中首先在TSP-STW问题的动态规划模型基础上，论述了计算机精确动态规划解法的求解策略和方法以及算法的有效性和复杂性，并将其成功应用于服务节点数相对较少的多小车单层配药服务模式中集中料斗的集药动作规划；在进行服务节点数较多的单小车多层服务模式中取药小车的运动规划时，为限制计算量和存储空间需求的迅速膨胀，引入以合理限制动态规划算法在每一阶段保留的最大状态元素数为核心的有限动态规划法，以便在求解结果的优化程度和规划时间上取得均衡，达到实时调度的要求。

This paper takes one low-speed-circumgyrate rocket with a empennage asa research object, set up a relevant reference frame, analyse the strength andmoment on the amended rocket, ratiocinate the sports equation with 6 DOF; analyse the factors which cause terminal windage between pratical trajectoryand fiducial trajectory, take certain rocket for example, make use of theemluator on the influence of estimating precision caused by measuredinformation, find the speed, the trajectory obliquity, the trajectory setoverand the coordinate are the sensitive factor arosing terminal windage of thetrajectory; introduce the developing status of detecting technique, and basedon the actuality, choose the radar in the ground as measure equipment; simplydesign and analyse the setting and inflame control of the impulse engine onthe amended rocket; design the amend method and validate its feasibility takingthe use of emluator.

本文以某型低速旋转尾翼火箭弹为研究对象，建立了相应的坐标系，详细的分析了作用在弹道修正弹上的力和力矩，由动量定理和动量矩定理推导出了在一般形式下的弹道修正弹的空间六自由度的运动方程；对引起弹道落点偏差的因素进行了分析，以某口径火箭弹为例仿真了可测信息量对估算精度的影响，发现速度大小、弹道倾角、弹道偏角和位置坐标是引起落点偏差的主要因素；对弹道探测技术发展现状作综合性阐述，并基于现状，选用地面火控雷达作为测量装置；对弹道修正弹上脉冲推力器的安装和点火控制方法进行了简要的设计与分析；设计了弹道修正弹指令修正的修正方法，通过数字仿真验证了方法的可行性。

Accurate station keeping is demonstrated in experiments with our four-DOF underwater vehicle and the observed target which is a regular tetrahedron with four ball-like culminations in our indoor water tank.

悬停定位具有两个特点：首先，它是一种动力定位，即在定位传感器的引导下，依靠自身的动力，在控制系统的指挥下抵抗外界扰动而保持某一位姿；其二，它是一种局部定位，水下机器人相对作业目标的运动空间范围一般不会很大。

For instance, in a famous passage in his final letter to Clarke, Leibniz claims that in order to obtain a representation of space, one can consider a system of objects, some of which are in motion, and abstract the notion same place from that system.
