權(quán)重窗口字段和按鈕
MV Weights（MV權(quán)重）
Name（名稱） 子控制器中操作變量的名稱。
**Damping Factor（阻尼系數(shù)） **操作變量的速度因子。
Weight（權(quán)重） 操作變量的權(quán)重因子。
CV Weights（CV權(quán)重）
Name（名稱） 子控制器中被控變量的名稱。
Deviation（偏差） 被控變量的工程單位偏差。
Weight（權(quán)重） 被控變量的權(quán)重因子。
若要將damping factors（阻尼系數(shù)）和/或deviations（偏差）切換到weights（權(quán)重），點擊列頂部的單選按鈕。選中單選按鈕的那一列是活動的。
輸入權(quán)重
Damping Factor（阻尼系數(shù)）列顯示了輸入阻尼系數(shù)的值。默認(rèn)阻尼系數(shù)值為1。第2列有字段用于輸入權(quán)重系數(shù)。權(quán)重自動計算將使用被控變量的穩(wěn)態(tài)增益（斜率被用于控制層）。
輸出權(quán)重
Deviation（偏差）列顯示了輸出偏差的值。默認(rèn)偏差值為1。第2列有字段用于輸入權(quán)重系數(shù)。Output deviation（輸出偏差）和weight（權(quán)重）值彼此呈倒數(shù)關(guān)系。
子控制器壓實點標(biāo)簽
選取壓實點
根據(jù)動態(tài)模型（解釋操作輸入對控制輸出作用）響應(yīng)，壓實點可以自動被計算。
Default in Use（默認(rèn)使用中）/Reset to Default（重置為默認(rèn)）切換按鈕：
? Default in Use（默認(rèn)使用中） - 指示壓實點可以根據(jù)穩(wěn)定時間（由子控制器動態(tài)預(yù)估）進行自動計算。
? Reset to Default（重置為默認(rèn)） - 激活基于穩(wěn)定時間（由子控制器動態(tài)預(yù)估）自動計算壓實點。
注1：（高級用戶）改變默認(rèn)壓實點將使自動計算壓實點功能失效，單擊Reset to Default（重置為默認(rèn)）按鈕恢復(fù)計算。此時按鈕將切換到Default in Use（默認(rèn)使用中）（已經(jīng)更改了默認(rèn)壓實點）。如果按鈕依舊顯示Reset to Default（重置為默認(rèn)），請務(wù)必確認(rèn)子控制器動態(tài)得到正確繪制。
注2：從PCTP2009起，對僅含斜坡的模型，其默認(rèn)輸入時域（壓實點）已經(jīng)由1改為100。用戶必須將此值手動調(diào)整到需要值。
子控制器壓實點曲線選項卡
用戶可以根據(jù)模型控制輸出對操作輸入的響應(yīng)來檢查輸出壓實點。請單擊Sub-controller Compaction Points Plots（子控制器壓實點曲線）選項卡進行檢查確認(rèn)。下圖顯示了Sub- controller Compaction Points Plots（子控制器壓實點曲線）選項卡的主要組成部分。
注：該響應(yīng)曲線是在取消每個被控輸出的公用延遲基礎(chǔ)上顯示的。

Weights Window Fields and Buttons
MV Weights
Name The name of the manipulated variables in the sub-controller.
Damping Factor Manipulated variable’s speed factor.
**Weight **Manipulated variable’s weighting factor.
CV Weights
Name The name of the controlled variables in the sub-controller.
Deviation Controlled variable’s deviation in engineering units.
Weight Controlled variable’s weighting factor.
To switch from damping factors and/or deviations to weights, click on the radio button at the top of the column. The column with the selected radio button is the active one.
Input Weights
The Damping Factor column shows the values for the input damping factors. The default damping factors are all equal to one. The second column has fields to enter the Weight coefficients. The automatic weight calculation uses the steady state gains of the controlled variables (slope is used for controlled levels).
Output Weights
The Deviation column shows the values for the output deviations. The default deviations are all one. The second column has fields to enter the Weight coefficients. Output deviation and weight values are the inverse of each other.
Sub-controller Compaction Points Tab
Selecting Compaction Points
Compaction points can be computed automatically from the response of the dynamic models that explain the effect of the manipulated inputs on the controlled outputs.
Default in Use/Reset to Default toggle button:
? Default in Use - indicates that the compaction points result from the automatic calculation based on the settling time estimate of the sub-controller dynamics.
? Reset to Default - activates the automatic calculation of the compaction points based on the settling time estimate of the sub-controller dynamics.
NOTE 1: (Advanced users) Changing the default compaction points makes the automatic compaction points calculation inactive until the Reset to Default button is clicked. At this point, the button will switch to Default in Use. If the Reset to Default button is shown (changes to the default compactions have been made), make sure to verify that the sub-controller dynamics are plotted correctly.
NOTE 2: As of PCTP 2009 the default input horizon (compaction point) has been changed from 1 to 100 for a ramp-only model. The user has to manually adjust this value to a desired one
Sub-controller Compaction Points Plots Tab
The user can check the output compaction points as a response of the manipulated inputs to the controlled outputs model. To perform the check, click on the Sub-controller Compaction Points Plots tab. The figure below displays the main components of the Sub-controller Compaction Points Plots tab.
NOTE: The response plots are shown after the removal of a common control delay per controlled output.
