Overview of Functionality
• Apromon is an online PID control performance
monitoring software.
• Apromon is very practical and easy for both
engineers and technicians in the control room.
• Apromon examines PID, multivariable PID,
cascade and override PID control quality based
on over 25 control and statistical performance
criteria.
• Apromon can monitor as many as 1000 to 3000
or more tags in any plant using modern OPC
technology.

Process Control Monitoring
• Process Control Monitoring is a rising, new
field.
• Plants can be run more efficiently with
control monitoring tools.
• As much as $300K to $2million/year
recurring savings can be realized by
modern control monitoring.

Features
• Generates a report automatically everyday,
identifying the worst control loops.
• Displays online grade report and diagnostic
message for all PIDs in the plant indicating their
health and control quality.
• Allows Control Engineers to quickly focus on the
loops deserving the most attention.
• Helps quick identification of control problems
and fast restoration of control quality.
• Novel and revolutionary ideas for monitoring.

• And many other diagnostic assistance tips for the control
room engineer and technician.

True Amplitude Detection (TAD)
-A Novel Invention
• PiControl Solutions company has invented
a new algorithm (TAD) to identify and
isolate the true amplitudes of process
signals.
• Competitor softwares report spectral
frequency that includes both high,
medium and low frequency noise.
• Only ApromonTM has the TAD capability
that pinpoints problems like never before.
• See illustrations on the next few slides:

Case 1: Perfect Sinusoidal Oscillation
The signal to the left shows
a almost perfect sinusoidal wave.
This has a single dominant
frequency.
Apromon determines the
single dominant frequency
as shown by the single bar
indicating one frequency.

Case 2: Noisy Sinusoidal Oscillation
The signal to the left shows a
noisy sinusoidal wave.
This has a single dominant
frequency, but also fast and
medium noise frequencies.
Despite any level of noise, drift and
disturbances, Apromon can isolate
the true oscillation and not confuse
with the noise and “squibbles”.
Other tools get confused depending
on the noise levels and frequencies.

PiControl’s True Amplitude Detection decomposes a signal into its real
amplitude and frequency

Case 3: SP Change and Random Oscillations
The signal to the left shows a
SP change. Control action is
non-oscillatory, spectral
distribution is diverse.
Apromon identifies the
Diverse spectral frequency
Distribution as manifested
By several bars (true amplitude
Detection) poles.

True Amplitude Detection (TAD) Algorithm
• The TAD algorithm helps to very accurately
determine which loops are truly oscillating.
• TAD allows various precision tuning parameters
to customize each loop to catch oscillations very
precisely.
• Irrespective of noise levels, squibbly data or
filtering or any other signal characteristics, TAD
provides the necessary handles to detect
oscillations without getting confused.

Extent of noise can be set
uniquely for every tag

The only software to break down a controller output into its
three individual contributions:
Proportional, Integral, Derivative (for EACH tag).
P, I, D Individual Contribution
Novel PCD Algorithm (PID
Controller Decomposition)
isolates the three pieces.
No other competitor software
provides this PCD feature- this
provides unique diagnostic
capabilities on PID Tuning.

Custom Diagnostic Message
and Grade for Each PID
Apromon computes a GRADE and a DIAGNOSTIC
MESSAGE for each and every PID in the DCS, thus
helping the control room personnel like an Expert
Advisor and an Auditing Grader.
