When Should You Use Derivative Action? (July 2002)

This web-based presentation explains when to use derivative action in your process plant. Derivative action can give the fastest response, but only if used responsibly. Too much derivative makes a loop unstable. Too little and it does little for the response and makes the valve jittery, wearing it out.

The presentation is available at no-charge, anytime, anywhere via a web browser and your Internet connection from:

    http://www.expertune.com/present.asp?name=derivative

Or from the presentation page at ExperTune.com:

    http://www.expertune.com/LearnCast.aspx

The reason to use derivative (or D) is that you can use more Proportional and especially more Integral action. The result can be a much faster reacting control loop. The effect of properly applied D (or derivative) action is most pronounced on second order processes like temperature loops. But, D action can help the response of most loops.

Track Your Plant's Performance in Your Web Browser (June 2002)

ExperTune's PlantTriage ® now lets you track the performance of your plant, unit operation or loop in a web browser. PlantTriage continually monitors the plant and assesses its performance. Prioritize, trend or view your plant's performance history using your web browser.

The browser-based views are self-customizable giving users the information they need, when they want it, in a format they can use. For example, these users have different needs and views on the plant:

  • Production Superintendent
  • Process Engineer
  • Process control Specialist or Technician
Operations Management will use the overview reports that show in a glance how a particular plant or unit is performing. The Process Engineer will view the Unit Operation Loop Performance List to see how his unit is performing and where the greatest gains are possible.

The Process Control Specialist or E&I Technician will want to see what loops will yield the greatest economic return if optimized. The Economic Performance Evaluation report will tell them which loops are the ones they should be analyzing and optimizing this week.

CD Shows Payback from Optimization (May 2002)

ExperTune and TOP Control have combined efforts to create a new CD: "The Payback For Optimizing Loops, a Management Brief". The CD shows how an investment of minutes per loop results in typical payback of weeks. It details the results of a computer control system installation with and without optimization of the control loops.

A manager has two choices for payback on the plant investment in computer control:

1) Invest in continuous improvement: The plant benefits more each year.
2) Do not invest: The benefits drop off after the second year.

The typical cost of a computer controlled loop including the valve, wiring, I/O, computer software and computer hardware is between $10,000 and $30,000. It takes roughly 50 minutes to optimize this loop with a cost of $100 to $300 or about 1% of the loop cost. The return on investment for optimization is often in hours but usually in a few weeks.

Enter your mailing address into http://www.expertune.com/PayBack and ExperTune will send you the CD.

ExperTune's full suite of optimization tools make it easy to increase the efficiency of your process. Use ExperTune's software to analyze and tune PID loops in any industrial controller.

How Does Your PID Loop Rate? (March 2002)

Optimizing control loops is a tradeoff between loop performance, robustness and valve wear. Now the ExperTune Control Loop Performance Evaluation lets you explore and analyze these tradeoffs in one glance.

The Performance Evaluation is a before and after analysis using bar graphs for easy comparison. The bars compare simulated industrial control loops using your current PID settings compared to new "what-if" PID settings. The loop's PV filter is also included in the analysis. In the performance and robustness section, higher bars are better. In the valve duty section, lower bars are better.

For both current and new settings, the performance bars show performance relative to optimal, with 100% being optimal. The robustness bars show how far away the loop is from being unstable. The higher, the better.

In the valve duty section, valve travel and reversals are compared for both current and new. Valve travel is the total distance the valve moves in a normally operating control loop with noise. The lower the bars, the better, since less distance would be traveled by the valve. Valve reversals are the number of times the valve changes direction. The less the valve changes direction, the less maintenance it will need. So again, a lower bar is better.

ExperTune's full suite of optimization tools makes it easy to increase the efficiency of your process. Use ExperTune PID Tuner/Analyzer software to analyze and tune PID loops in any industrial controller. ExperTune PID Tuner/Analyzer includes powerful simulation, modeling, robustness, linearization, valve wear analysis, pH linearizer, time series analysis, multivariable, statistical, frequency response, and loop tuning tools. ExperTune's PlantTriage software ensures your entire plant is running at peak performance. PlantTriage monitors, assesses and optimizes the performance of each loop in the plant.

Baseline your Plant for Better Performance (February 2002)

ExperTune's new PlantTriage baselines the performance of your plant for future comparison. Compare your plant against the baseline to see how the changes you make improve the performance.

PlantTriage continually monitors and assesses the performance of each area in the plant giving you complete control of how you baseline or compare performance. For the assessment of each loop in the plant you can set a baseline of performance and a threshold to not exceed.

Using PlantTriage templates, you can easily set-up the baselines for a unit operation, group of loops, or the entire plant. Graphically zoom to a time window when the plant was operating well, or where you want to establish a baseline and press "set baselines".

Use PlantTriage default templates or completely customize your own for complete control of baseline and threshold performance settings. The templates let you customize the setting of baseline and threshold assessments, from a time window you choose, by selecting minimum, maximum, average, X number of standard deviations, a fixed value, or no change. Apply the templates to a unit operation, entire plant or a group of loops you define.

For example, you may want to baseline the average error of the PV for all flow loops using assessments from last week. Select the appropriate template, zoom in on the window of data from last week, and click "set baselines". At the same time, your template could specify a threshold limit over which you do not want the average error to exceed. For example, you can set templates for flow, temperature, pressure, any group of loops, unit operation or the entire plant.

PlantTriage continually monitors the plant and assesses the performance against the baselines and thresholds you define. Trend any assessment against its baseline, or prioritize loops needing attention based on how close assessments are to thresholds.

ExperTune's full suite of optimization tools makes it easy to increase the efficiency of your process. Use ExperTune software to analyze and tune PID loops in any industrial controller. ExperTune includes powerful simulation, modeling, robustness, linearization, valve wear analysis, pH linearizer, time series analysis, multivariable, statistical, frequency response, and loop tuning tools.
