Application

VarSpecalteration:Variables are clasified into six types of variable specification suchas "Constant","Calculated",etc.Specificationalterationallows you to change the specification ofa variable to change its fixed variable and free variable roles in each mode of operation.

EO variable value configuration:Specify information about allvariables,seting thevalue,unit,lower limit,upper limit,step limit,boundary type,and scale.

Using EO variable value configurationsand VarSpecalteration,the function of back-calculating process conditions based on the requirements of the model's target parameters is realised.VarSpec alteration determines the fixedand freevariable roles,and EO variable value configurationdeterminesthe target values of the variables.

Gainanalysis:Solves the partial derivativerelationship between fixed and free variablesaccording to the currentmodel structureandvariable values.

ProductApplicationScenarios Real-timeoptimization(RTO)

RTOOperating Principle

Real-time optimization is theprocess of obtaining real-time processdata and operating conditions of the device.It iscaried out under the premise of meeting the planning and scheduling objectives.The aim is to maximize production eficiency.This isachieved byadoptingasteady-state mechanism model based on equtionoriented models to optimize the operating parametersof the device.Theoptimized operating parametersare then fed back into the control system to carry out the optimization process.

APEXmodelingapplications

With functions such as "VarSpec alteration"
"EOvariablevalue configuration""Objective
Functions"and "Gain Analysis,"processmod
elingand debugging processes for RTO ap
plicationscanbe performed.Thedata recon
ciliation and optimization objective function are created and solved in the corresponding operating mode to obtain a data calibration orsolution optimization.

Product Application Scenarios- -Advanced Process Control(APC)

The Advanced Process Control(APC)adjusts the manipulated variables in response to the controlvariable settings based on the gainobtained from the device'sstep test and the process controllogic.Typically,whenan APC systemis implemented inaplant,normalandstableoperating conditionsareselected,and theequipment is perturbed to obtain a batch of gains around the current operating conditions.
However, this method of obtaining gains has the following problems:
Requirementsfor the operating conditionsof the plantare strict
Gain isonly valid when the operating conditionsare similar to the step testconditions.Higher the devia
tion,worse the results are
Step test that disturbs the devices may interrupt the normal production process

The "gainanalysis"functionof this platformsolves thepartialderivatives in thesystemof model equations andthroughonlineoperation,the gain ofthe manipulated variablesoverthe controlvariables canbe obtained undereach operating condition.Bylinking theAPEXplatform with theAPC software,itispossibletoobtain theoperatingdataof thedeviceonline and update thegainof the relevant variables to theAPCsystem in real time,without having toperturb thedevice toobtain thegain.Inthisway,therealtimeandeffective stable control of the devices is guaranteed.
