When an order is form in position machine, the needed breeds and quantity of cigarette will be established and thesequence and time of cigarette sorting in an order will be also established, so before sorting an order, the order'length can be compute, but before sorting an order, the order's space is existenced as a virtual space, thus supposed a virtual space which loaded finished cigarette and order when virtual space arrive the corresponding sorter, plc control the time parameter and activated the sorting, and the sorter sorting cigarette to virtual space, an order accomplished.

对件烟行走时间进行了建模并提出了一种烟草自动分拣算法，当订单在上位机生成后，所需烟品种及数量随之确定，因此订单中所要分拣的烟分拣的次序及分拣的时刻也就可以确定，所以在订单分拣之前，订单的长度是可以计算出来的，而在未真正分拣之前，订单的长度是一个&虚拟存在的空间&，应用逆向推理的过程可假设一个装成品烟和订单的&虚拟空间&，当&虚拟空间&到达对应的分拣机位置时，通过plc对订单中件烟时间参数的控制，分拣机自动分拣件烟至&虚拟空间&完成订单分拣，该算法实现方便并能节约大量的硬件成本，对其他一些物流分拣行业也具有一定的推广价值。

Combined system simulation with optimal control, selected a typical water cooled primary/secondary chilled water system, used the research achievements of Annex 30 in IEA for the reference, this work firstly presents both the basic component models and the control system component models. Secondly gives the main models for parameter identification and experiment validation. Finally a dynamic digital simulator is set up using TRNSYS as the platform to substitute a real system to test and evaluate some kinds of online optimal supervisory control strategies after giving some essential data file input and finishing all the PID controllers'tuning.

本文将空调系统的仿真模拟与优化控制相结合，首先选择比较典型的水冷式二级泵集中空调系统，在国际能源组织IEA第30子课题Annex 30多年研究成果的基础上，建立了系统各设备的部件模型和控制系统部件模型，对主要模型参数的辨识方法进行分析，同时对其准确性给予验证；在此基础上，建立了以TRNSYS为仿真平台的集中空调水系统数字仿真器；通过必备数据文件的输入和对所有下位机控制回路PID参数的调试，最终完成可用于评估各种上位机优化控制方案的空调水系统数字仿真器。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
