An air traffic management and control system is software provided by ground-based controllers to direct aircraft on the ground and through controlled airspace. It can also provide advisory services to aircraft in non-controlled airspace. The primary aim of air traffic management and control systems is to prevent collisions, organize and expedite the flow of traffic, and provide information and other support for pilots. In some countries, air traffic management and control systems are operated by the military and play a crucial role in security and defense.

Radar is an object detection system that makes use of radio waves to ascertain the range altitude, direction, and speed of approaching and still objects. It is used to detect missiles, spacecraft, ships, aircraft, weather formations, and terrain. It is used as an early-warning device to spot an enemy's airborne systems and approaching missiles from great distances, and for surveillance, ground control interceptions, and long-range early warnings. It is mainly used by defense establishments.

针对硅片传输机器人末端低频振动问题，提出了一种基于最优S曲线轨迹的硅片传输机器人低频振动的抑制方法。该方法通过推导在参数化S型曲线输入条件下非线性时变系统的动态响应近似方程得到系统低频振动的振幅方程，并通过优化振幅方程中的S型曲线参数使得低阶振动振幅达到最小值，从而实现低频振动的抑制。首先对硅片传输机器人进行运动学、末端位置误差以及刚柔耦合动力学建模并进行动态特性分析。随后推导了在参数化S曲线输入条件下系统末端的时域动态响应方程近似解析解与振幅方程近似解析解，并根据硅片传输机器人自身的动态特性给出了最优S曲线参数计算方法。最后分别通过数值仿真分析与实验对该方法进行验证。实验结果表明，应用该方法后硅片传输机器人末端x方向的低频振动的振幅降低了53.9%，y方向的低频振动的振幅降低了45%。

在冗余度机器人的避障规划问题中，当障碍影响机器人末端运动时，避障运动和机器人的末端轨迹跟踪运动会发生相互冲突。针对这个问题，提出了基于主从任务转化的避障算法。该方法将避障运动的操作空间定义为1维的运动空间，引入了2个转换变量，可以根据得到的实时最小距离的变化,实现机器人末端的轨迹跟踪运动和避障运动之间光滑连续的优先级转换。最后，通过对一个3自由度平面机器人的仿真实验，对算法的正确性进行了验证。结果表明，机器人与障碍物的最近距离大于0.02m，并且机器人末端可以准确地到达目标位置。所提出的方法不仅能实现冗余度机器人的避障，而且能防止任务之间的冲突。
