搭建流程模型
概述
SMOCPro過程模型使用三種不同類型的輸入：
?操作變量（MV）- 控制器可以操作的過程輸入。
?測量干擾（DV）- 控制器可測量，但不能操作的過程輸入（例如氣候變化）。
?不可測擾動（UNM）- 未測量的（如噪音）過程輸入。它描述了可能的模型誤差來源。
請參考教程部分獲取更多信息。
模型構建器模塊的設計是為了創建新的過程模型和/或從AIDAPro（過程識別軟件）中輸入模型。該模塊還允許用戶使用流程-表格型的圖形模型生成器（GMB）查看和/或編輯現有的流程模型。
在工作區設置和/或打開后，選擇建立過程模型的方法。請參閱使用工作區部分以獲得關于打開或建立工作區的詳細信息。
建立模型
若要編輯或修改一個過程模型，在工作區窗格窗口左側點擊模型構建器模塊。
模型窗口字段和按鈕
|||
| ------------- |:-------------:| :-----:|
| Model（模型） | 顯示工作區中的模型。|
| Type（類型） | 顯示工作區中每個模型的類型，如控制器或仿真模型。|
| Status（狀態）| 顯示每個模型的當前狀態。如果模型已經被編譯且未被修改，該選項是 “Up to Date(最新的)” ，如果流程模型在編譯后被修改，則是“Out of Date(過期的）。|
| Select（選擇）| 選擇工作的模型。|
| New（新）| 創建一個新的模型。|
| Delete（刪除）| 刪除高亮的模型。|
| Copy（拷貝）| 復制高亮顯示的控制器/仿真模型，并將其作為新仿真模型的模板。|
| Rename（重命名）| 重命名高亮的模型。|
| AIDA Import（AID A輸入）| 向高亮模型輸入AIDAPro模型。如果沒有模型存在，則將創建一個新模型。|
創建新模型
單擊Models窗口上的New（新建）按鈕后，彈出下面的對話框。
1、默認名稱顯示為model，但用戶可以輸入一個不同的模型名。
2、新模型被創建，在點擊OK按鈕后，其名稱出現在模型列表中。

Building a Process Model
Overview
SMOCPro uses process models with three different types of inputs:
?Manipulated Variable (MV) – Process input that is manipulated by the controller.
?Measured Disturbance (DV) – Process input that is measured but not manipulated by the controller (such as weather variations).
?Unmeasured Disturbance (UNM) – Process input that is not measured (such as noise). It describes the source of possible model errors.
Please refer to the Tutorials section for more information.
The Model Builder module has been designed to create new process models and/or import models from AIDAPro (process identification software). The module also lets the user view and/or edit existing process models using the flow-sheet-type graphical model builder (GMB).
After your workspace is set up and/or opened, select the method for building the process model. Refer to the Using a Workspace section for detailed information about opening or setting up a workspace.
Setting Up a Model
To edit or modify a process model, click on Model Builder module in the workspace pane on the left hand side of the window.
Models Window Fields and Buttons
|||
| ------------- |:-------------:| :-----:|
|Model |Displays the models in the workspace.
|Type| Displays the type of each model in the workspace, either controller or simulation model.|
|Status |Displays the current state of each model. The options are either “Up to Date” if the model has been compiled and not changed, or “Out of Date” if any modification to the process model has been made since the last compilation.|
|Select| Select the model to work with.|
|New| Create a new model.|
|Delete| Delete the highlighted model.|
|Copy| Copy the highlighted controller/simulation model to use as a template for a new simulation model.|
|Rename| Rename the highlighted model.|
|AIDA Import| Import AIDAPro models into the highlighted model. If no model exists, a new model is first created.|
Creating a New Model
After clicking the New button on the Models window, the following dialog box opens.
1.A default name is displayed for the model but the user can enter a different model name.
2.The new model is created and its name appears in the model list after clicking the OK button.
