The design and commissioning of the controls associated with a continuous or batch process directly impact plant operating efficiency and production quality and throughput. In this session we review techniques that may be used to identify control opportunities to reduce production costs, minimize variations in product quality and to maximize production within the limits set by market demand. Several common application examples from the process industry will be used to illustrate how plant production rate and product quality are directly influenced by process control variation and constraints in plant operation. Starting with an assessment of control loop utilization and automatic control performance, a step by step process is outlined that may be used to identifying and addressing areas where it is possible to justified the time and material costs required to improve control performance. In particular, information will be provided on how to quickly tune single loop control of self-regulating or integrating process and to recognize when variations in control loop performance are not associated with loop tuning. An overview will be provided of tools and techniques that may be used to achieve best control performance over a wide variety of operating conditions. Also, guidance will be provided on when it is possible to justify the cost associated with the installation and commissioning of multi-loop techniques such as feedforward control, ratio and override control. The steps required to commission multi-loop control strategies will be address along with common mistakes to avoid. Also, input will be provided on how to recognize when advanced control techniques such as Fuzzy logic or MPC are needed to achieve the desired control performance. At the end of this session a drawing will be held to give away 10 copies of “Control Loop Foundation – Batch and Continuous Processes”. Many of the ideas discussed in this session are addressed in this book.

Practical Advanced Process Control for Engineers and TechniciansLiving Online
In today's environment, the processing, refining and petrochemical business is becoming more and more competitive and every plant manager is looking for the best quality products at minimum operating and investment costs. The traditional PID loop is used frequently for much of the process control requirements of a typical plant. However there are many drawbacks in using these, including excessive dead time which can make the PID loop very difficult (or indeed impossible) to apply.
Advanced Process Control (APC) is thus essential today in the modern plant. Small differences in process parameters can have large effects on profitability; get it right and profits continue to grow; get it wrong and there are major losses. Many applications of APC have pay back times well below one year. APC does require a detailed knowledge of the plant to design a working system and continual follow up along the life of the plant to ensure it is working optimally. Considerable attention also needs to be given to the interface to the operators to ensure that they can apply these new technologies effectively as well.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

3. Session Objective
Provide a roadmap that may be used to maximize the
return on your control investment
4. Agenda
Assessment of control loop utilization and automatic
control performance,
Identifying areas where it is possible to justified the
cost of improving control performance.
Tools and techniques to achieve best control
performance. Identifying and correcting field
problems.
5. Evaluating Control System Utilization
Product quality and
manufacturing efficiency
may be impacted by
variation in key
parameters.
When production is
process limited, then
throughput may be
increase by reducing
process variation and
operating closer to the limit.
The control must operate
as designed to achieve
these benefits.
6. Control Utilization
Control utilization is an indicator that can be used to
quickly determine if control and measurement problems
exist within a control system. Surveys indicate that the
primary reasons for control not being fully utilized fall
into two areas:
Field measurement or control element
Process or control design
An immediate improvement in control utilization will be
achieved by addressing these problems. To achieve full
utilization, improved communications between
maintenance and operations is important.
7. Example – Case Study
At one pulp and paper plant a snapshot of the control utilization was
collected to quantify the state of the process control. This survey showed:
Control Normal
Loops Mode Utilization
Bleach Plant 78 60 76%
Power House 185 130 70%
Pulp Mill 174 116 66%
Paper Mill 236 134 56%
An instrumentation team was formed to investigate loops that were not
running in their normal design mode. This team was responsible for making
sure measurement, control valve, and process problems were addressed in
a timely fashion. The reduction in variability led to significant improvements
in plant throughput and product quality

15. Tips for Using On-Demand Tuning
Set step size large enough to insure the response to
the PID output changing is larger that the
measurement noise and influence of process
disturbances.
Select “Integrating” if the process is not self-
regulating.
If the process has low or high gain, then selected
Default Process and set the process type to match
the expected behavior.
16. Manual Tuning (Not a DeltaV System)
When commissioning PID control associated with a self-regulating
process, this procedure may be quickly applied to both old and new
control systems to determine the tuning for PI control.
The size of the step should be just large enough to easily distinguish
the resulting change in the controlled process output.
17. Manual Tuning - (Not a DeltaV System)
Alternate
When commissioning PID control associated with a self-regulating
process, this procedure may be quickly applied to both old and new
control systems to determine the tuning for PI control.
The size of the step should be just large enough to easily distinguish
the resulting change in the controlled process output.
Tune as follows:
– Place the PV and OUT on a trend.
– Place the controller in Manual and allow the process to reach steady sate.
– Impose a step change in OUT and observe the response
– Set the RESET equal to ¼ of the time it takes to “almost” line out (98% of final
value)
– Set the GAIN equal to 1/3 of process gain, Kp where
– Kp = ((Δ%PV) / (Δ%OUT) (Be sure to convert to % of span!)
– Place the loop in automatic and make small adjustments to the Setpoint and
observe the response. Adjust ONLY the GAIN to achieve the desired response.

placed in automatic

detect if a valve or

changes in the PID
output.
Cycling can not be
eliminated through
tuning.
19. Valve Positioner Recommendation
The most common problems in commissioning a control system
can often be traced to the fact that a positioner has not been
provided with the valve, or the positioner provided with the valve
has not been properly installed or has malfunctioned.
– The rule of thumb is that to achieve best control
performance, all regulating valves should be equipped
with a positioner.
– Without a positioner, the control performance that may be
achieved is very limited when a valve is sticking – which is
inherent in most valves.
– The cyclic behavior caused by a sticky valve (with no
positioner) cannot be eliminated through tuning. Changes in
tuning will only impact the period of the cycle that develops.
The only way to eliminate this type of behavior is to install a
valve positioner.
20. Installed Characteristics.
7000 From a control perspective, it is
highly desirable that the process
6000 gain be constant. If the process
gain is constant, then the same
5000 proportional gain may be used
over the entire operating range of
Gas Flow (SCFH)
4000 the control loop.
If the valve characteristic was not
3000 been selected based on the
process requirements, then the
2000 installed characteristic could be
non-linear.
0
As illustrated in this example, the
0 20 40 60 80 100
Valve Position (%)
process gain varies from 0.5 to 4;
that is, the process gain changes
by a factor of eight.
21. Impact of Non-linear Installed Characteristics
Non-linear Process Example
Process gain and dynamics may change as a function of
operating conditions such as valve position or feed rate.
22. Linearizing Response
To compensate for
the changes in
process gain, a
characterizer block
may be installed
between the PID and
Analog Output
blocks. Select the
option to inverse the
calculation done in
the forward path for
the PID back
calculation to allow
bumpless transfer.

28. Split Range Control
One of the most common
ways of addressing multiple
process inputs is known as
split-range control.
The splitter block may be
used to define a fixed
relationship between the
controller output and each
manipulated process input –
appearing as one valve to the
PID block
The setup must account for
the gain associated with
each process input to
achieve consistent control
behavior.
29. Example – Steam Header Pressure
To allow the plant to continue operation if the turbine or generator fails
and must be shut down, pressure reducing valves (PRVs) between the
high pressure header and the lower pressure header may be adjusted
to meet the lower pressure header steam demand and to maintain the
header pressure constant.
This may be accomplished by using a splitter block in conjunction with
a PID block to adjust the pressure reducing valves.
30. Steam Header – Splitter Characterization
If the valve sizes or operating conditions for the valves are different, then it is
necessary to characterize the splitter to compensate for these differences.
For example, if the flow ratings in thousand of pounds per hour, KPPH, of the
valves used in split-range control were as shown below:
– Valve 1 flow rating = 50 KPPH
– Valve 2 flow rating = 150 KPPH
Then the controller output range of adjustment associated with Valve 1 would
be:

36. Reducing Control Variation
When tuning is not sufficient to achieved the desired
level of variation in critical control parameter or to
maintain it at an operating limit, then multi-loop
techniques may sometimes be applied to improve
control. Three common multi-loop techniques are:
Feedforward Control
Cascade Control
Override Control
37. Summary
An on-line measurement of control utilization and
variability is provided by DeltaV Insight.
Exploring the causes of poor utilization is the first
step in resolving measurement, actuator or control
issues.
When single loop control is not sufficient to achieve
the desired level of control the multi-loops solutions
should be explored.
