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 Industrial Tool for the Control Room

and a Training Tool for Research and Teaching in Colleges.

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).

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 the AC which has slow and complex dynamics.

PID Tuning OptimizationFirst, set the CV range, in our example,

range of the AC (analyzer controller)

Next, set the MV range, the

output range of the AC

The entire process of PID Tuning including

Only 3 Minutes and

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.

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.

PITOPS is a Comprehensive Industrial

Process Control Solutions Pitops works with any DCS or PLC brand, vendor or model.

Pitops can be applied to super-fast dynamics like compressors and turbines at millisecond scan rates.

Pitops works with all PID loops like Flow Control, Pressure Control, Level Control and Temperature Control, etc.

Pitops works with super-slow PID loops like Online Analyzer Controllers scanning in minutes and with very slow settling times of over 5 hours.

Pitops calculates Control Valve Stiction during Identification and includes Stiction during PID Optimization.

Pitops can be used on Nonlinear Processes.

Pitops includes PID Output Rate of Change as an explicit constraint during PID Optimization, a unique function unmatched by competitors.

Pitops supports Gap Action and Deadband on PID simulation and optimization.

PITOPS Unique Functions

Works entirely in the simpler time domain (no need for Laplace and Z-domain knowledge). Other products use Laplace, Poles/Zeros.

Works with super-slow PID loops like Online Analyzer Controllers scanning in minutes and with very slow settling times of over 5 hours.

Works with highly oscillatory data in closed-loop Auto/Cascade Modes.

Identifies transfer functions even if data has large noise and unmeasured disturbances.

Identifies Control Valve Stiction; includes stiction during PID tuning optimization.

Works on MIMO (multiple input/multiple output) systems, multiple cascades, multiple masters going to a selector and also Fan-Out PID systems.

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.
