Process Control Consulting for
PID Tuning
& plant-wide optimization.

Process control consulting optimizes PID controller performance, reduces control loop oscillations, and increases plant throughput by systematically identifying and correcting suboptimal tuning parameters — delivered on-site and remotely for industrial plants in 40+ countries.

6 consulting services40+ countriesNo plant step tests

Every PiControl engagement applies our process control software directly at your facility — PITOPS for closed-loop system identification, SUPERTUNE for automatic online PID auto-tuning, COLUMBO for closed-loop MPC model identification, and APROMON for live loop performance monitoring. Our engineers arrive with the same software that runs in customers' production plants — not spreadsheets and generic methods.

Our 6 process control consulting services

Four optimization disciplines (PID, APC, MPC, process improvement) and two adjacent engineering services — every engagement scoped against measurable KPIs and documented with before-and-after results.

Core optimization servicesSwipe
APC GAIN+4%

DCS / PLC – based Advanced Process Control (APC)

APC implementation designs and commissions DCS-resident advanced process control that runs inside your existing DCS or PLC — no external host computer, no proprietary middleware. Traditional APC projects degrade after turnarounds because the optimization layer lives outside the control system; DCS-resident architecture avoids that failure mode entirely.

DifferentiatorSurvives DCS upgrades
MPC RE-STABILIZEDNOW

Model Predictive Controller (MPC) Maintenance and Improvement

MPC maintenance audits, tunes, and re-optimizes existing MPC applications from any vendor — AspenTech DMCplus, Honeywell Profit Controller, Yokogawa Exasmoc, Shell SMOC. Most MPC applications lose 30–50% of original benefit within two years; closed-loop re-identification restores it without rebuilding the controller.

OutcomeRestored in 1–2 weeks
ENERGY & EMISSIONS

Process Improve — Reduce Steam Consumption, Flaring, Emissions, Alarms and More

Process improvement consulting reduces steam consumption, minimizes flaring, controls emissions, and prevents product losses through control-loop-level optimization — not plant redesign. The work targets loops that drive utility cost and environmental footprint: combustion air ratio, fuel-gas pressure, distillation reflux, compressor anti-surge, boiler drum level.

FocusEnergy · emissions · flaring
Adjacent engineering servicesSwipe

These two services complement the optimization-layer engagements above when customers need both a new control system and an optimization layer on top of it, or when engineering design feeds into a downstream PID or APC engagement.

PLC / SCADA

PLC / HMI / SCADA Design and Programming

Builds and modernizes plant-floor control systems with rigorous loop-by-loop documentation, tested control narratives, and operator interfaces designed for fast situational awareness. Covers greenfield, brownfield, and legacy replacement projects.

ScopeLayer 2 — DCS/PLC
PROCESS DESIGNFEED

Innovative Chemical Engineering Technology Design

Applies first-principles process modeling and dynamic simulation to debottleneck, redesign, and optimize unit operations — distillation revamps, heat exchanger network redesign, reactor studies, pump and compressor selection.

The protocol

How a PiControl consulting engagement works

A four-stage protocol identical for on-site and remote delivery — only the engineer's location changes.

Define the work

Scoping

Site assessment, control-loop inventory, KPI baseline, and engagement boundary. Output: a scope document listing which loops, which KPIs, which DCS/PLC platforms. Duration: 3–5 working days.

Why PiControl

Why plants choose PiControl consulting

Poorly tuned loops, drifted APC controllers, and degraded MPC applications quietly bleed throughput, raise utility costs, and force constant operator intervention. Most consulting follows one of two patterns: a generalist with a spreadsheet and Ziegler-Nichols, or a DCS-vendor team selling licenses for tools you already own. Neither produces durable improvement. PiControl is structured to avoid both.

Most consulting
The PiControl way
01

Generic tools

A generalist with a spreadsheet and Ziegler-Nichols, or a DCS-vendor team selling licenses for tools you already own.

Our own software

Every engagement runs on PITOPS, SUPERTUNE, COLUMBO and APROMON — the same process control software we license to customers. The only variable is who runs it.

02

Disruptive or abstract

Open-loop step tests that upset production, or frequency-domain math that misses how real plants actually behave.

Closed-loop, time-domain

Closed-loop system identification in the time domain — controllers stay in automatic, no bump tests. It captures dead time, nonlinearity and interactions frequency-domain methods miss.

03

Vendor lock-in

Vendor teams that lock the tuning, APC and MPC layers to their own DCS and their own licenses.

Independent of any DCS / PLC

The optimization layer runs inside any control system — Honeywell, Emerson DeltaV, Yokogawa, ABB, Siemens PCS 7, Rockwell, Schneider. No vendor lock-in for the tuning, APC or MPC layers.

Where our engineers work

Industries where our engineers work

Every engagement is tailored to the process dynamics, safety constraints, and regulatory environment of the specific industry — refining loops tune differently from pharmaceutical batch reactors.

FAQ

Frequently asked questions about PiControl consulting

Engagement length, on-site vs remote, plant size, platforms, ROI, and cost.

Process control consulting is an engineering service that diagnoses and corrects suboptimal PID tuning, advanced process control performance, and MPC model accuracy in industrial plants. The work uses process control software — closed-loop identification tools, automatic tuning calculators, and live performance monitors — applied by engineers on-site or remotely via OPC.
Engagements run 1–12 weeks depending on scope. A focused PID tuning engagement on 50–100 loops completes in 2–3 weeks. A full APC implementation on a multi-unit plant runs 8–12 weeks. MPC re-optimization on a single controller is usually 1–2 weeks.
Both. Engineers deliver consulting on-site at the plant or remotely via OPC-DA / OPC-UA connection to the historian. The methodology is identical — the software does the same identification and tuning math whether the engineer is in the control room or in another country. Most engagements combine an initial on-site scoping visit with remote execution.
Engagements cover a typical range of 50–500 control loops. Small skid units and pilot plants with fewer than 20 loops are also in scope, as are very large refineries and ethylene crackers with thousands of loops phased across multiple engagements.
PiControl process control software connects to every major DCS and PLC platform via OPC-DA and OPC-UA — Honeywell Experion, Honeywell TDC3000, Emerson DeltaV, Yokogawa CENTUM VP, ABB Ability Symphony Plus, Foxboro IA, Siemens PCS 7, Rockwell PlantPAx, Schneider EcoStruxure, Allen Bradley PLC. No proprietary hardware or middleware required.
Every engagement is scoped against measurable KPIs — variability standard deviation, energy intensity, throughput, emissions, flaring volume — captured before parameters change and again after deployment. In a recent power plant engagement covering 80 boiler loops, SUPERTUNE auto-adaptive tuning reduced combustion oscillation by 55%. Typical payback: 3–6 months.
Yes. Consulting can be paired with process control training courses — PID tuning fundamentals (PID100), advanced PID (PID475), APC fundamentals (APC200), DCS/PLC operator courses. Pairing consulting with training makes engagement benefits durable: trained engineers maintain the optimization after the consultant leaves.
Cost depends on loop count, on-site vs. remote delivery, plant complexity, and travel scope. Schedule a consultation for a scoped proposal — the first call is free and includes a high-level estimate.
