控制器設(shè)計與仿真
這是一個基于Windows的軟件包，與AIDAPro集成，用于設(shè)計，測試和構(gòu)建Exasmoc控制器。AIDAPro生成過程動態(tài)模型。或者，可以使用Graphical Model Builder構(gòu)建模型。SMOC-PC允許仿真控制器行為來測試整定，模型誤差魯棒性和優(yōu)化性能。離線設(shè)計的最后階段是創(chuàng)建控制器文件（.EXA），供在線Exasmoc控制器使用。
有關(guān)AIDAPro和Exasmoc離線設(shè)計的說明可在PCTP SMOCPro-PC用戶指南中找到。
DCS接口定義
DCS接口定義模塊將根據(jù)應(yīng)用從DCS分配控制器輸入/輸出。
離線設(shè)計的最后階段是創(chuàng)建定義文件（.EXA），供在線Exasmoc控制器使用。
PCTP SMOC-PC用戶可以使用AIDA和Exasmoc離線設(shè)計指令。
Exasmoc在線控制器
在線控制器包含了實時控制器所需的所有功能。包括信號驗證，初始化，模式摘除，標(biāo)準(zhǔn)操作員和工程師界面以及控制器引擎。如前所述，Exasmoc在線控制器是基于Windows，運行于Exasmoc站的控制器。
本手冊向用戶提供了用于實際工廠中APC控制模式下的Exasmoc在線控制器的控制，操作，監(jiān)控和配置/調(diào)優(yōu)功能的分步說明。
? Exasmoc的補充軟件包
補充軟件包（COAST和RQE）補充了基于Exasmoc的APC策略。這些軟件包的使用將取決于過程的類型和APC方案的需求。
COAST：控制應(yīng)用標(biāo)準(zhǔn)
這是一個應(yīng)用于石油，天然氣，化工和石油化工連續(xù)加工的綜合性高級控制模塊庫。 COAST模塊通常與Exasmoc結(jié)合使用，提供支持控制功能和所需的過程計算，以實現(xiàn)特定應(yīng)用所需的控制和操作目標(biāo)。
參見圖3.0a顯示的一個示例。“塔盤負(fù)荷計算”（COAST庫中的一個模塊）提供了Exasmoc的計算。
以下是COAST庫中某些模塊的列表。
殼牌浪涌量控制（SSVC）：
SSVC是一種先進(jìn)液位控制器，旨在通過充分利用可用的喘振容量來最大限度地減少進(jìn)料流量變化對下游單元的影響。
熔爐線圈平衡：
該控制器通過調(diào)節(jié)線圈流量設(shè)定點來平衡爐膛出口溫度。
Controller design and simulation
This is a Windows based package, integrated with AIDAPro, to design, test and build Exasmoc controllers. AIDAPro generates the process dynamic model. Alternatively, the model may be built using the Graphical Model Builder. SMOC-PC allows to simulate the controller behavior to test the tuning, robustness to model errors and optimization performance. The final stage in the off-line design is the creation of the controller file (.EXA), for use by the on-line Exasmoc controller.
Instruction for AIDAPro and Exasmoc offline design are available in PCTP SMOCPro-PC user guide.
DCS interface definition
DCS interface definition module will assign the controller inputs/outputs from/to DCS according to applications.
The final stage in the off-line design is the creation of the definition file (.EXA), for use by the on-line Exasmoc controller.
Instruction for AIDA and Exasmoc offline design are available in PCTP SMOC-PC user.
Exasmoc on-line controller
The on-line controller incorporates all functions required for the operation of the controller in real time. This includes signal validation, Initialization, mode shedding, standard operator and engineer interface, and controller engine. The Exasmoc on-line controller is the one, which runs in Windows, based Exasmoc station described earlier.
This manual provides the step-by-step instructions to the user for the control, operation, monitoring and configuration/tuning functions of Exasmoc online controller for actually controlling the plant in APC mode.
? Supplementary packages for Exasmoc
Following supplementary packages (COAST and RQE) complement the Exasmoc based APC strategies. The use of these package will depend upon the by type of process and need of APC scheme for it.
COAST: Control Application Standards
This is a comprehensive library of advanced control modules for standard applications to continuous process in oil, gas, chemical and petrochemicals. COAST modules are generally used in conjunction with Exasmoc, and provide the supporting control functions and process calculations needed to achieve the desired control and operating objectives for a particular application.
Refer figure 3.0a, where an example is shown. “Tray Loading Calculations” (One of the module within COAST library) provides calculations for Exasmoc.
Following is the list of some of the modules from the COAST library.
Shell Surge Volume Control (SSVC):
SSVC is an advanced level controller, designed to minimize the effect of feed flow changes on down stream units, by making the best use of available surge vessel capacity.
Furnace Coil Balancing:
This controller is used for balancing furnace coil outlet temperatures, by adjusting the coils flow set points.
