Field Experience in Property

Estimation

DeltaV Neural has been used in a variety of applications as a soft sensor for property estimation. Also, the estimated property may be used in closed loop control applications. In this short course we will present the features of DeltaV

Neural, some of the implemented applications, and also some of the challenges and issues faced in developing a soft sensor. Dynamic simulation will be used to illustrate how a property estimator may be easily created from operating data.

Approach to Quality Control

• Where Analyzers are available (and reliable) use them for

Controlled Variables ( and Disturbance Variables ).

• Use intermediate measurements to estimate Quality when

Analyzers are not functioning.

• Develop Virtual Sensors when Online Analyzers are not practical

Introduction to Quality Estimators

• Small Process Models that provide an indication of stream Quality from Process measurements.

• Applications:

– When an Analyzer is not available.

– When an Analyzer is unreliable or in maintenance.

– When an Analyzer response is dynamically slow due to Analyzer sample processing time (eg, GLCs).

– Process equipment between where the Quality is determined and where the stream is available for sampling.

Purpose of Quality Estimators

• To assist in operations achieving Quality Targets and Quality

Constraints using Lab Results as the feedback mechanism.

• To improve the performance of closed loop Quality Control.

– FeedBack or FeedForward Control

– Model Predictive Constraint Control

• To give Real Time Optimization a means to predict the Qualities resulting from its (potential) adjustments.

Quality Estimator Formulation

• GENERAL FORMULA ...

– Quality = f ( Temperature, Pressure, Flow ) + Calibration Constant

– Many Estimators are a function of pressure compensated temperature.

• Function may be a simple constant term:

– E.g. K * ( Temperature )

– Some estimators are complex nonlinear functions

• Functions based on first principles

• Functions based on empirical data

– Statistical techniques

– Artificial Neural Networks

Modeling & Analysis Approaches

– First principles-based models

– Statistical Approaches

– Nonlinear Regression

– Neural Networks

First Principles-based Modeling

Based on physical and chemical relationships

Examples: Kinetics, Fluid flow,

Thermodynamics

Based on decades of experience

Can be highly accurate when process is well understood and relatively stable

Requires in-depth knowledge of process

 Does not account for process behavior changes over time

• Sometimes available through combustion unit manufacturer

Statistical Approaches

• Techniques such as:

 Data analysis/curve fitting

Regression techniques

Probability analysis

• Require lots of data

• Require understanding of statistical techniques

• Better for analysis than modeling

Neural Network-based Models

 Fairly new in the marketplace

 Practical

 Minimal process knowledge is necessary

 Easy to apply to a variety of applications

 Training requires good data

 Easily re-trained to adapt to new conditions

 Do not extrapolate well

Emerson Value Addition

• Familiarity with DeltaV Neural

• Process Expertise

• Neural Net Modeling Expertise

Leads to:

• Faster Implementation

• Lower Risk

• Appropriate Application

– Alternative approaches considered

– Taking the next step to control

Oops!

• I thought I had a good model…

– But it doesn’t look so good on new data

• I thought I had lots and lots of data…

– But the model isn’t as good as advertised

– How much data do I really need

• I thought for sure that this variable was critically important…

– But DeltaV Neural ignored it

Practical Considerations

• Data is the key

– Correct time-stamps

– Raw snapshot data - no data compression

– Sufficient variability

– Data Density – clustering and voids

• Don’t confuse correlation and causality

Data Requirements

• DeltaV Neural can capture dynamics…

– but time stamps must be accurate

• Time delays should be constant or compensated

– Selection of time to steady-state is critical

• Auto-correlation can lead to unusual results

Data Requirements

Quality of empirical data

– Use raw (snapshot) data, avoid filtering and averaging

– There must be variability and it should span the range of expected operation

– Minimal Data Clustering and Data Voids

– Signal to noise ratio must be high

– Correlation vs. causality

Data Requirements

Quantity of empirical data

– More is usually better

Data Requirements

Know the process

– Avoid redundant information

– Ensure dominant affects are incorporated

– Use calculated variables (first principles based inputs)

– Understand process dynamics

Common Questions

• How many samples do I need?

– Technically

• Complexity (number of inputs and time to SS vs sample interval)

• Train vs test split & verify unseen data

– Practically

• > 100 is good rule of thumb

• Why was this variable deselected?

– Redundant

– No variability

– Too much noise

– Bad measurements

– Bad timestamps

– Correlated w/out causality

Troubleshooting

• Verify views

– Predicted & Actual vs Sample

• Identify trends

• Identify nature of error (bias, peak offset, etc)

– Predicted vs Actual

• Identify clustering and voids

• Identify outliers

• Analysis w/ Excel (Pre-processing)

– Plot variables

• Vs Time

• Vs Actual

• From least to greatest

– Statistical checks

• Max, Min, Delta (span)

• Mean, Median, midpoint

• Standard Deviation & 6 Sigma

Controlling Product Quality

• Direct Analyzer : product property measured by On-line Analyzer.

• Inferential : product property inferred from product state or another product property.

– Utilizes easy to measure states or properties to infer properties that are difficult or impossible to measure on-line.

• E.g. Temperature and pressure of vapor leaving top tray of a column indicating composition of top product

Provide redundancy for online analyzers with poor availability/reliability

Direct Analyzer Control

• Pros of Direct Analyzer Control

– Accuracy, good repeatability

NIR now available e.g for on-line octane

– Reduces lab, work

– Faster results than lab

• Cons of Direct Analyzer Control

– Expensive

– High level of mechanical maintenance required to retain accuracy

– Sample extraction

– Often non-continuous read-out.

Inferential Control

• Pros of Inferential Control

– Inexpensive - No capital cost.

– Less mechanical maintenance.

– Continuous read-out

– Faster to implement from scratch.

• Cons of Inferential Control

– Models often inaccurate, particularly if non-linear.

– Potentially high maintenance if no On-line Analyzer available ( i.e. monitoring and updating of correlations )

– Generally, test runs must be done to develop accurate relationships

Often limited rangeability.

Developing New Models

• Monitor Model Performance

– Trend vs Lab Analyses

• Identify if error is random or persistent

• Identify source of error

• Update Model as Required

– Correlation with New Data

• Short term variance > Adjust Bias

• Long term variance > Recalculate Correlation (New Model)

• Test New Model

– Verify Against Old Data

– Continue to Trend vs Lab Data

Introduction

• Neural Networks

– When to use them and when not to

– Selecting Inputs

– Data Robustness

– Offline Training

– Overview of SFK’s Neural Networks

– Problems, Solutions, Troubleshooting, and Tools

When to use and when not to

• When not to use a Neural Network

– Process Models or Equations are already well established

Selecting Inputs

• Use as many inputs as possible. Unimportant inputs may be ignored.

• Inputs should not be related.

• Use calculated values instead of raw inputs if relationships are known.

• Inputs must vary over the range in which the

Neural will be used.

• Unmeasured Disturbances can hurt.

Data Robustness

• Inputs must vary over a range. The NN output is not valid outside the range of training.

SFK’s Neural Networks

• Two Neural Networks were required

– Extracted Kappa

– D1 Brightness

• DeltaV sits on top of Foxboro I/A

• Communications via OPC

• NNs provide feedback to MPC (Model Predictive

Control) loops.

Extracted Kappa NN

• Look at the inputs

Extracted Kappa NN

• Evaluate the

• Should make sense

• Adjust the time delays if necessary

Extracted Kappa NN

• Train the NN

Extracted Kappa NN

• Check the validity of the predictions.

• This can be an iterative process

Error Checking and Overrides

• NN Provides

Signal to MPC for Control

• Check for Errors to provide

Overrides

Problems Commissioning Delig

• Initially, we could not get a good fit.

– A couple of inputs were dependent (co-linear) on other inputs. Eliminated these inputs and replaced with others.

– Also introduced calculated inputs where possible.

Problems Commissioning Delig

• Neural output unstable for MPC

– Due to noise from the inputs. Added extra blocks to allow the NN inputs to be filtered separately.

Problems Commissioning Delig

• Neural Net Output went uncertain

– Major cause was inputs going outside the trained ranges.

– Retrained Neural with larger set of data. Needed to use PI-Datalink to pull data out and combine multiple time periods into one file.

– Offline training with this data provided a more robust

Neural Net.

Problems Commissioning Delig

• Neural Net Output went uncertain

– Built tools to pinpoint the problem.

– Build error checking into the configuration to look for range issues and take action if an input causes a problem.

Brightness NN

• After the learning curve on the Extracted Kappa

Neural, we were ready to attempt the Brightness

Neural.

• Several attempts were made at getting the

Neural Net to fit.

Could Not Achieve a Good Fit

• Statistical

Hint – If the pattern looks like a shotgun blast, it is a bad thing.

Problems

• Large Variations in Dead Times.

• Time Stamping of Lab Entries.

• Repeatability of Lab Tests.

• Data rangeability poor over training set

• Unmeasured Disturbances – due to not having input measurements for all necessary variables greatly affect the brightness .

Brightness NN Plan 2

• Develop Dynamic Estimator based on published data.

• Modify Lab Test to provide minor biases to the

Estimator.

Trouble Shooting Tools

• Excel Spread

Sheet using both

PI Datalink and

DeltaV Excel

Addin to Pinpoint

Problems

Trouble Shooting Tools

• Process History View will give a good indication of dynamics.

Off Line Training

• The expert mode allows sensitivity analysis from

.dat files.

• Provides capability to combine data from multiple time frames.

• Data Manipulation can clean up noise and unwanted disturbances.

What Lessons Were Learned?

• Careful up front design time will save a lot of time later.

• Use care in selecting which data to use in training the Neural Networks.

• Time Stamping is extremely important even on slow acting processes.

• A Neural is a good tool provided prerequisites are available.

Problems and Solutions

• Neural Network may need different filtering than other processes

– Use Second Input (AI or Pseudo AI) to provide secondary filtering.

• Output will be invalid outside the trained range

– Check valid ranges and program error handling

Problems and Solutions

• Historian does not hold enough information to cover full sets of inputs.

– Increase Historian Archive capabilities by increasing the number of archives and/or size of archives

– Use PI Datalink or other tools to save data into Excel spreadsheets. Combine data and use off line training

Summary

• Neural Networks are a very powerful tool.

• The Extracted Kappa Neural Net and associated

MPC provide a good solution for our customer.

• The Brightness Neural Net attempt shows that the NN is not a magic solution for all cases. In this case, the addition of instrumentation would have allowed the Neural to work.
