Gas phase composition is controlled by a cascade PID analyzer controller (AC),
whose output (OP) manipulates the setpoint (SP) of a slave flow controller.
We illustrate the tuning of theAC which has slow and complex dynamics.

Parameters Identified:
DeadTime=18 minutes
Process Gain=32.8
Time Constant=35.8 minutes
Notice there are no step tests in the MV
(this is complete closed-loop data)

11. PID Tuning Optimization
First, set the CV range, in our example,
range of theAC (analyzer controller)
Next, set the MV range, the
output range of theAC
Now we proceed to PID
Tuning Optimization

12. Optimize PID Tuning
Next, click on “Optimize PIDTuning”

13. The entire process of PID Tuning including
transfer function identification took…..
Only 3 Minutes and
10 Clicks
And it was so Easy, Fast and
Convenient!
No other competitor software,
technology or algorithm can match the
power, ease and functions of PITOPS

Pitops optimizes PID tuning for the
custom plant needs comprising of
typical Setpoint change, and typical
noise and disturbances seen in the
plant. Pitops tuning optimization is
proven to be superior to any other
technology or rules published
worldwide. Simulations can be built
and made to mimic the real plant in
just minutes.
Pitops optimized tuning results are not just
heuristic-based and are superior to IMC, Lambda
Tuning, Ziegler-Nichols, Cohen-Coon and others.

15. Multivariable
Identification
Pitops can process multivariable inputs and outputs (MIMO systems). See
a three input multivariable identification below. Pitops identifies Three

20. PITOPS can Identify Control Valve Stiction
even with closed-loop data with multi-inputs

21. Multiple Cascades
Pitops can be used to tune any number of cascade PIDs in a long chain.
The whole process takes just minutes and is very novel and simple.

22. Feedforward Control, Constraint Overrides,
Model-Based Control, Inferential Control
Pitops is not only a
transfer function
