间隔管理（IM）是下一代航空运输系统（NextGen）和单一欧洲空中交通管理研究（SESAR）的一部分。间隔管理的目标是在IM飞机和指定的目标飞机之间实现更精确的间隔。由IM飞机机载的航空电子设备使用由ADS-B接收的来自目标飞机的状态信息计算的速度命令由IM飞机执行，以便实现相对于其目标飞机的期望的间隔时间。在一些IM操作中，预期将形成IM飞机的串，其中每架飞机相对于其紧接在前的飞机间隔开。在为IM飞机计算速度指令的速度控制律的设计中，不仅要检查一架飞机相对于另一架飞机的性能和稳定性，而且要检查整个弦的性能和稳定性。字符串行为从根本上影响在某些环境中成功实现间隔管理的潜在操作实用性。本文提出了一个简化的，封闭形式的字符串稳定性分析的时间历程的速度控制律，已提出了间隔管理。仿真结果验证了封闭形式的分析，并被用来评估字符串的行为和系统性能的方法间隔操作。
Interval Management (IM) is a concept being developed as a part of the Next Generation Air Transportation System (NextGen) and Single European Sky ATM Research (SESAR). The objective of Interval Management is to achieve a more precise spacing interval between an IM aircraft and an assigned target aircraft. Speed commands, calculated by avionics onboard the IM aircraft using state information from the target aircraft received by ADS-B, are implemented by the IM aircraft in order to achieve a desired spacing interval relative to its target aircraft. In some IM operations, it is expected that a string of IM aircraft will be formed, where each aircraft is spacing relative to its immediately preceding aircraft. In the design of a speed control law that calculates speed commands for the IM aircraft, one must not only examine the performance and stability of one aircraft relative to another, but also the performance and stability of the entire string. String behavior fundamentally affects the potential operational practicality of successfully implementing Interval Management in certain environments. This paper presents a simplified, closed-form string stability analysis for a time-history speed control law, which has been proposed for Interval Management. Simulation results are shown to validate the closed-form analysis and are used to evaluate string behavior and system performance for an approach-spacing operation.
