| U-Tune PID Tuning Package | ||
|
The U-Tune PID Tuning package was produced after years
of problem solving and tuning for the North Sea oil and gas industry. Although
the vast majority of processes can be characterised by
simple delay-lag dynamics, many expensive tuning
packages fail to cater for the excessive noise and
disturbances typifying the process response.
U-Tune succeeds by giving the process control engineer direct input into the process identification phase and by providing easy comparison of test results.
The tuning
algorithms have been thoroughly tested on compressor
anti-surge and load sharing controllers, separator level
controllers, produced water and water injection control
systems, flaring, export control and much more.

| U-Tune PID Tuning Calculator | ||
|
The PID tuning
calculator uses the same
tuning algorithm as U-Tune but without the process
identification and tuning parameter management
features. Simply type in the process gain, delay and
lag time as obtained from step tests and the
calculator will provide tuning parameters for your
process controller.
The User Guide gives full
information on performing step tests with examples
from ideal and real process controller response
characteristics.

I spend
approximately 120 days each year offshore embedded
in process and control issues of many different
types. To help me in this work, I have developed a
whole range of software tools and calculators, not
just the PID tuning packages shown on this page.
Some day, I may even find the time to productise a
few of them. Until that time, my consultancy clients
will get the benefit of the following and other
packages:
Tuning parameter variability analysis to examine the spread of the process model estimates, primarily to ensure that stability constraints are not exceeded. Conversion of compressor controller inputs into the anti-surge process variable. For example, the calculation of S for CCC controllers required for accurate tuning of anti-surge controllers. Proximity to surge analyser to view the applicability of the configured compressor surge line and the approach path of the compressor operating point towards surge. |
