15、 Compaction Points（压缩点）选项具有下述默认值。最后一点的值根据Compaction Points Plot（压缩点绘图）选项中看到的过程设定时间选择。
16、 作为一个额外的目标，设定一个经济函数以最小化Duty（能源）。
17、 生成控制器。
仿真
生成控制器后你可以使用多种模式仿真它的行为，如优化或进料干扰反响。
创建一个默认的仿真场景：
18、 单击树节点中的Simulation（仿真）文件夹，然后单击New（新建）。
19、 接受默认名。
这将打开控制器/模型选择窗口，其中默认仅可选择可用的控制器和仿真模型。
如果你想针对过程模型失配测试多个控制器设计，你需要建立相应的控制器并搭建其它仿真模型（在Model Builder中）。如果它们可以被选择，那么这些新加的过程模型和控制器将出现在该窗口中。
该默认场景将执行以下事件：
•在第5步控制器状态将由Standby（挂起）改为control（控制）；
•在第5步将添加一个进料流量（Feed flow DV）在10分钟内按一定斜率增加500吨的行为；
•在第100步控制器状态将由control（控制）改为optimize（优化）。
请按照这些步骤定义之前的仿真事件。在场景节点顶部的单选按钮可用来切换所有的或相关的参数显示。单击Display Relevant Step 1（显示相关第1步）单选按钮隐藏无关的仿真设置。
20、 在General（常规）选项卡中，设定下列参数：Economic Function Selection（经济函数选择），Tracking Filter（跟踪滤波）和Economic Coefficient value（经济系数值）。
21、 在Sub_Debutanizer选项卡中，填写操作点信息、质量和负荷控制要求。
22、 单击Hide Step 1（隐藏第1步）并输入以下建议的场景事件：General（常规）选项卡中的控制/优化控制器模式和Sub_Debutanizer选项卡中的Feed flow（进料流量）斜率。
要访问仿真设备，请选择树节点中的Plot （绘图）。
在运行仿真时，你可以观察到回流量和再沸量的改变，以及质量和塔板负荷的变化。
原文：
- The Compaction Points tab has these defaults. The last point values are chosen according to the settling time of the process as seen in the Compaction Points Plot tab.
- As an additional objective, set an economic function for minimizing the Duty.
- Build the controller.
Simulation
After the controller is built you can simulate its behavior in multiple modes such as optimization or reaction to feed disturbances.
Create a default simulation scenario: - Click on the Simulation folder in the tree nodes and click New.
- Accept the default name.
This opens the Controller/Model selection window where, by default, the only Controller and Simulation model available are selected.
If you want to test various controller designs against process model mismatches, you need to build the corresponding controllers and create other simulation models (in Model Builder). These additional process models and controllers will appear in this window where they can be selected.
The following events will be used to perform this default scenario:
• At step 5 the controller status will change from Standby to control,
• At step 5 a Feed (DV) flow ramp increase of 500 tonnes over 10 minutes will be introduced, and
• At step 100 the controller status will change from control to optimize.
Follow these steps to define the previous simulation events. The radio buttons at the top of the Scenario node can be used to toggle the display between all and relevant parameters. Click on the Display Relevant Step 1 radio button to hide settings unrelated to this simulation. - In the General tab, specify the following parameters: Economic Function Selection, Tracking Filter and Economic Coefficient value.
- In the Sub_Debutanizer tab, fill in the operating point information and control specifications on the qualities and loading.
- Click on Hide Step 1 and enter the following suggested scenario events: control/optimize controller mode in the General tab and Feed flow ramp in the Sub_Debutanizer tab.
To access the simulation facility, select Plot in the tree node.
While running the simulation, you can see the moves in Reflux and Reboil and the variations in Qualities and in the Tray Load.
