摘要
研究运输机空投优化控制问题,针对当前重装空投模型假设条件苛刻,难以贴近实际且缺少连投模型的问题,放宽"空投典型情形"基本假设,改进了传统的分离体建模方法,详细推导了重装空投过程载机和货物的全量动力学模型,提出了在连投时引入两个控制变量ГA,ГB∈{0,1},以描述货物不同的空投阶段,建立了全量的连投模型,模型扩展性强,可完成n件货物的空投数值仿真。最后,通过仿真对单投与连投时载机开环动态响应进行了量化分析,并对空投时间间隔的对载机影响进行了对比分析,保证了空投的安全性。
In view of the harsh assumptions of Current Heavy - weight Airdrop Model, it is difficult to be close to reality and lack of Sequential Airdrop model. In the paper, the assumptions of ＂typical situation of the airdrop＂ were broadened, the traditional separation modeling method was improved, and the full amount of dynamic model was deduced in detail. The introduction of control variables ГA, ГB ∈ {0,1 } was proposed to indicate different airdrop stage of cargo. Full dynamics equation of aircraft and cargo in heavy - weight sequential airdrop was established. The model is of scalability and numerical simulation of n piece of cargo airdrop can be achieved. Dynamic response of single or sequential airdrops was compared and the influence of different airdrop interval was analysed.
