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/yearrecurring 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.

Benefits Examples• Which loops are not controlling well?• Which loops are oscillating?• Which loops have matching frequencies?• Which control valves are not working well?• Which control valves are moving excessively?• Which loops need proportional adjustment?• Which loops need integral adjustment?• Which loops need derivative adjustment?• Which loops need filter adjustment?• What is onstream factor of the loops?• Which loops do the operators intervene most?• Which loops have instrument signal problems?• 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.

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).

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.
