Apromon is an AI-based (artificial intelligence based) online software product for monitoring the PID loop control performance of primary and Advanced Process Control (APC) loops. Apromon evaluates single loops, cascade loops, any Advanced Process Control (APC) loops and even signals that have PV only but no controller associated them. Apromon is AI based CLPM (artificial intelligence based control loop performance monitoring software).
Apromon has the unique power to automatically convert flow controllers, pressure controllers, temperature controllers, level controllers, online analysis controllers, any Advanced Process Control (APC) controller into a single “grade” factor, just like the grade given by a professor to a student on a test or an examination. 100 indicates best performance and 0 indicates the worst.
The program can be made to run as fast as every 15 minutes though typically an auto-run every 2-6 hours is more common. Clicking on the “Show Grade Trends” displays Figure 2 showing the current and past historical Grade of tags selected by the user.
Apromon displays 25 different performance criteria for every tag. The Grade reported for each tag is a function of these criteria. Some of the performance criteria are displayed in Figure 3. Apromon also assigns a text descriptive message describing the performance of the tag; e.g. “Control performance is satisfactory”, “Loop oscillates- high (PV-SP) error” etc., see Figure 4 for an illustration. These messages and the Grade are extremely valuable and are stored in the historical archival system that comes with Apromon. The user can easily access the text message and the Grade for months and years.
Apromon is equipped with leading-edge technology for oscillation detection. Apromon identifies “True Amplitudes” by decomposing a plant signal into its true signal and isolating any noise and signal strength not related to the process. Apromon also comes with a one-of-kind Spectrum analysis algorithm. The true-amplitude-detection (TAD) arrays and Spectrum distribution are shown in Figure 5. This technology is not available in any other software product. Furthermore, Apromon reliably determines if any of the loops are starting to hunt (oscillate) or become unstable with growing amplitudes.
Configuration and implementation of Apromon is very simple and quick. Configuration parameters are shown in Figures 6 and 7. The entire process of configuring Apromon and getting it to work takes only about 4 hours. All data interface is via easy-to-use screens and with standard Excel-based data exchange.
