A2 功能概述
為了使用Exasmoc控制器,用戶必須熟悉Exasmoc規范,尤其是先進過程控制的功能概述術語。接下來的部分將提供此信息。
A2.1控制器規范
Exasmoc集成模型預測控制和優化控制器由主控制器和子控制器組成。集成優化控制器可以在子控制器之間共享控制結果。一個子控制器對應于一個常規MVC控制器。SMOC集成優化控制器的特點如下所示。
? SMOC控制器由兩層結構組成。第一層用于集成第二層最優控制的執行。第二層的處理被稱為子控制器,在一個SMOC控制器中可以有幾個子控制器。第一層的處理被稱為主控制器。
? 可以通過在子控制器之間接收和傳遞中間變量來建立控制器之間的關系。因此,可以延伸兩個或更多子控制器以構建大規模先進控制。
? 下面寫了控制器規格的最大數量。 超出此范圍的控制器的行為將得不到不保證。

| Sub Controller (子控制器) | 每個主控制器最多50個,每臺PC 250個。|
| MV | 每個子控制器最多100 MVs,每個主控制器最多500個,每臺PC總共180 MVs。|
| CV | 每個子控制器最多200個CVs,每個主控制器最多250個。|
| DV| 每個子控制器最多50個DVs,每個主控制器最多1000個。|
| POV| 每個子控制器最多200個POVs,每個主控制器最多1000個。|
| EF | 每個主控制器有一個EV。|
| Economic Function(經濟函數)| 每個主控制器最多50個,每臺PC 250個。|
| Economic Function Coefficient(經濟函數系數)| 每個主控制器最多500個,每臺PC 2000個。|
| GAIN(可在線更改)| 每個主控制器最多500個,每臺PC 2000個。|
| Prediction points (預測點)| 每個MV或CV最多60個。|
*數目按照R3.05更新,同時它也取決于安裝的硬件。

A2. Functional Outline
In order to use Exasmoc controller it is necessary for user to get acquainted with Exasmoc specifications and especially terminology in view of its functional outline for Advanced Process Control. Following subsequent section will be providing this information.
A2.1 Controller Specification
Exasmoc integrated model predictive control and optimization controller is composed of Main Controller and the Sub controllers. The integrated optimization controller can share the control results among sub controllers. One sub controller corresponds to one conventional MVC controller. The features of SMOC integrated optimization controller are shown as follows.
? One SMOC controller is composed as two hierarchies. The first hierarchy is integrated to perform optimum control with the second hierarchy. The processing of the second hierarchy is called a sub controller, and can have several sub controllers in one SMOC controller. The processing of the first hierarchy is called a Main controller.
? It is possible to establish relationship between controllers by receiving and passing the intermediate variables between sub controllers. As a result, it is possible to build a large-scale advanced control to extend over two or more sub controllers.
? Maximum number of the controller specification is written below. The behavior of the controllers beyond this specification is not guaranteed.
