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.
