2. What is PITOPS?
It is process control software for industries
and universities.
It identifies transfer functions.
It optimizes PID tuning parameters.
It can be used to design APC (Advanced
Process Control) inside the DCS or PLC.
It is an IndustrialTool for the Control Room
and aTrainingTool for Research and
Teaching in Colleges.

3. PITOPS is a Major New Invention
 Pitops identifies multivariable transfer functions
with closed-loop data in just minutes!
 Pitops tunes PIDs precisely meeting plant needs.
 Pitops can be used to develop APC (Advanced
Process Control) systems inside the DCS or PLC
much better and less expensive than MPC (model
predictive control).

4. PITOPS algorithm is
new and superior to
any other technology
from any competitor

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.

7. Read Plant Data from Excel or OPC
Pitops then reads PID PV,
the ControlledVariable
Pitops also reads PID OP,
the ManipulatedVariable
We specify the
Excel Filename
First, Pitops reads data
from Excel or OPC.

8. Select Transfer Function Order
Gas Composition
PV Data
AC Output Data
Next, we chose the
Model Order – First
Order in this case.

9. Identify Transfer Function

10. Transfer Function Parameters
The BLUE trend is theTransfer
Function Model Prediction
See transfer Function
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”
Notice the Setpoint Change, BlueTrend
See the optimized PV Response
Examine theAC (PID) OP – OutputTrajectory

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
transfer functions simultaneously using complete Closed-Loop data.

Identification is based on purely Closed-Loop Data (No

Three transfer functions
(2nd Order + DeadTime)
are simultaneously Identified

17. PITOPS works with Oscillatory Data
(Competitor tools FAIL with such data )

18. PITOPS Complete Closed-Loop Identification

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
identifier and PID
tuning optimizer
but has the
functions to design,
implement and
tune Feedforwards,
Constraint Control
Schemes, Model-

Inferential Control
Schemes.

23. Advanced Process Control (APC) in DCS/PLC
Pitops has all
functions needed to
design DCS or PLC
resident APC
(advanced process
control) in a novel
and convenient
manner, far superior
to current
technologies.
In many cases,
performance of a
Pitops-based
DCS/PLCAPC can
be superior to an
MPC.

24. PITOPS is a Comprehensive Industrial

 Requires far less data (1/5th or less) compared to competitor products.
 Can be used on Nonlinear Processes for Gain Scheduling/Adaptive Control.
 Includes PID Output Rate of Change as an explicit constraint during PID Optimization, a unique
function unmatched by competitors.
 Supports Gap Action and Deadband on PID simulation and optimization.
 Optimizes tuning based on SP change + Disturbances + Noise as exactly seen and
encountered in DCS/PLC – unmatched by competition.
 Takes 5 minutes to install, 2 hours to learn. User manual less than 60 pages!
 Allows changing transfer function & PID tuning parameters to simulate what-if cases.
