Continuous online recalculation
Recalculates PID parameters every 1-5 minutes based on real-time process dynamics.
SUPERTUNE is fully automatic, auto-adaptive online PID tuning and optimization software built by PiControl Solutions. Powered by an AI-based algorithm, SUPERTUNE runs continuously inside the DCS or PLC and recalculates PID parameters every 1-5 minutes based on real-time process dynamics, with no manual intervention required after initial configuration. Where PITOPS performs closed-loop system identification and PID tuning for a defined study, SUPERTUNE keeps tuning loops on an ongoing basis, matching gains to the process as conditions change.
Most PID loops are tuned once, at commissioning or during a periodic PID tuning consulting visit, and left alone until performance visibly degrades. Between visits, fouling, catalyst aging, feed-quality swings, and load changes quietly shift the process dynamics the original tune was based on, and the gains decay. SUPERTUNE closes that gap: it identifies process dynamics continuously and adjusts PID parameters in the background, so tuning holds between engineering visits instead of drifting.
SUPERTUNE runs continuously inside the DCS or PLC via an OPC connection, identifying process dynamics from normal closed-loop operating data and recalculating PID parameters every 1-5 minutes, no step tests or bump tests and no engineer standing by. Because it operates fully automatically once configured, SUPERTUNE keeps PID loops matched to the process long after a one-time tuning study or an embedded relay auto-tuner would have gone stale.
Recalculates PID parameters every 1-5 minutes based on real-time process dynamics.
No manual intervention required after initial configuration.
Identifies process dynamics and computes optimal gains without step tests.
Deploys via an OPC connection and operates continuously inside the existing control system.
Tracks fouling, catalyst aging, feed-quality swings, and load changes automatically.
Auto-tuning becomes active within hours of configuration.
Plants deploy SUPERTUNE on loops whose dynamics change faster than periodic re-tuning can keep up: compressor anti-surge and speed loops that shift with fuel quality and load, boiler and turbine loops during load-following duty, and reactor, column, and exchanger loops affected by fouling, catalyst aging, or feed-quality swings. SUPERTUNE runs in the background inside the DCS or PLC across these loops without engineer intervention.
PiControl's PID tuning consulting engagements set loops right first, then hand off ongoing tuning to SUPERTUNE. The consulting engagement establishes the baseline tune across the loops that matter most; SUPERTUNE keeps those gains from decaying between visits by recalculating controller parameters every 1-5 minutes as conditions shift.
For a broader look at auto-tuning methods and when continuous adaptive tuning is the right fit, see the PID auto-tuning overview.
SUPERTUNE's feature set is built for one outcome: PID loops that stay tuned continuously, without an engineer visiting every drifting loop.
Recalculates PID parameters every 1-5 minutes based on real-time process dynamics.
Keeps loops tuned as dynamics shift, rather than waiting for the next scheduled tuning visit.
No manual intervention required after initial configuration.
Frees engineers from repetitive re-tuning work on loops that drift between visits.
Identifies process dynamics and computes optimal gains without engineer trial-and-error.
Replaces manual trial-and-error tuning with continuous closed-loop identification.
Deploys via an OPC connection directly into the existing control system.
No separate control layer to maintain; gains write directly into the existing controller.
Identifies process dynamics from normal closed-loop operating data.
No production disturbance and no trip risk during tuning.
Auto-tuning becomes active within hours of configuration.
Plants see continuous tuning benefit almost immediately after deployment.
PID controllers account for over 95% of all control loops in industrial plants, and most of them are tuned once (at commissioning or during a periodic tuning visit) and then left alone. Between visits, the process dynamics those gains were based on keep moving: heat exchangers foul, catalyst ages, feed quality shifts, and load changes with the production schedule. None of that shows up as a single dramatic failure; it shows up as gains that quietly decay until a loop is oscillating, sluggish, or riding a constraint nobody planned for.
A tuning study identifies process dynamics from the operating conditions in front of the engineer that day. Move throughput, feed composition, or load away from that point and the identified model, and the gains derived from it, no longer match the process.
Plants running dozens to hundreds of loops per unit cannot economically send an engineer back every time fouling or catalyst aging shifts a handful of loops. Re-tuning visits are scheduled periodically, leaving an open window between the drift and the fix.
Embedded DCS or PLC auto-tuners compute a set of gains and stop; they don't keep watching the loop afterward. As soon as conditions change, the tune they produced is still the same tune, whether or not it still fits.
SUPERTUNE removes the gap between tuning visits: continuous, automatic recalculation of PID parameters, running inside the DCS or PLC, adapting to the process as it moves. For loops that need a baseline tuning study first, PiControl's PID tuning consulting combines the two.
SUPERTUNE is one part of PiControl's process control software suite, paired with system identification, model maintenance, and performance monitoring across the loop lifecycle.
Before deploying SUPERTUNE, plants often run PITOPS for closed-loop system identification to establish a baseline tune from normal operating data. SUPERTUNE then keeps that tune from decaying by recalculating gains every 1-5 minutes on an ongoing basis.
Where SUPERTUNE keeps PID loops tuned continuously, COLUMBO refreshes degraded MPC models from existing closed-loop data without pulling the controller out of automatic mode, the multivariable counterpart to SUPERTUNE's single-loop auto-adaptation.
APROMON monitors PID and APC loops continuously for oscillation, valve degradation, and tuning drift, surfacing exactly which loops would benefit from SUPERTUNE's continuous auto-adaptive tuning.
SUPERTUNE runs on PID loops across every sector PiControl serves, wherever fouling, catalyst aging, feed variability, or load changes cause tuning to drift between visits.
SUPERTUNE runs continuously on production PID loops in plants worldwide, part of the same closed-loop tuning methodology behind 10,000+ PID loops tuned and 50+ MPCs re-stabilized across 200+ industrial facilities since 2005. "SUPERTUNE keeps our compressor loops on target around the clock," reports one process control engineer. "We stopped chasing tuning drift after every grade change."
