此圖顯示了在抗干擾方面令人滿意的行為海诲。然而在圖的右半邊需要更快的優(yōu)化职车，因為Duty（能源）最小化響應較為緩慢蜡吧。
25茬底、 返回到方案編輯器中并將Economic Function Tracking Filter（經(jīng)濟函數(shù)跟蹤濾波）（在General選項卡中）修改為1.0搭儒。這使得經(jīng)濟優(yōu)化跟蹤速度大大加快穷当。

SMOCPro 環(huán)境提供給用戶快速編譯模型從而搭建控制器盏道，以及在離線仿真環(huán)境中仿真的能力稍浆。軟件的控制器節(jié)點可被用于定義子控制器，修改控制器參數(shù)摇天，定義經(jīng)濟優(yōu)化函數(shù)以及指定所需的子控制器行為粹湃。仿真節(jié)點可用來測試當控制器投在線時可能遇到的較為廣泛的各種情況。
原文：
- In the Plot section select the SubCont01:Sub_Debutanizer variable list to have the plot display all relevant variables related to the sub-controller problem.
- Run 200 steps of simulation and zoom in for 250 steps to get:
This plot shows satisfactory behavior in disturbance rejection. However, faster optimization is desired since the Duty minimization is slow in the second half of the plot. - Go back to the scenario editor and change the Economic Function Tracking Filter (in the General tab) to 1.0. This results in much faster tracking of the economic optimum.
- Now perform some fine-tuning on the manipulated variable weights, for example, the Reflux moves could be penalized more.
- Go back to the scenario editor and set an event to change the Reflux Weight. If you want this tuning to act from the simulation start, modify this Weight in the Weight tab under the sub-controller node of the controller itself and (re)build the controller.
- Go back into the simulation plot to see how the behavior of the closed loop process has changed.
Take Home Message
The SMOCPro environment provides the user the ability to quickly go from compiling a model to building a controller and simulating it on an offline simulation environment. The Controller node of the software can be used to define sub-controllers, modify controller tuning, define economic optimization functions as well as specify the desired sub-controller behavior. The simulation node can be used to test a wide spectrum of circumstances that may be encountered by the controller once it is implemented online.

**Case 2: Reactor (Hydrotreater Type) Quality Control **
(\Program Files\ShellGlobalSolutions\PCTP\Tutorial\SMOCPro\Tutorial2_ReactorCL.wsp)
(\Program Files\ShellGlobalSolutions\PCTP\Tutorial\SMOCPro\Tutorial2_ReactorPID.wsp)
The figure below shows a simplified process flow scheme for reactor control. The process feed is heated in a furnace and passed on to a reactor where a reaction takes place. The reaction is controlled by the feed inlet temperature of the reactor (TC1) and by a quench gas flow (FC).
The objective of the process is to obtain a product of a certain quality, measured at the reactor outlet stream (QI). Also, the temperature in the reactor (Temperature) should not exceed a certain maximum value.
Because of variations in the properties of the fuel gas and the settings of the pressure controller, the furnace outlet temperature can have some non-negligible variations. The temperature controller ultimately rejects these; but the transient effect of the variations needs to be properly identified to perform tight reaction control.
