What We Do - APC
We specialize in three main areas
APC
Model Predictive Control Technology
Autonomous Possible APC leverages cutting-edge Model Predictive Control (MPC) technology developed by our technology partner, expert with over 35 years of research in system identification and multivariable control.
The system combines real-time process modeling, optimization, and control to deliver a robust supervisory layer on top of traditional PID loops, allowing plants to safely operate closer to limits and achieve higher profitability through smarter control decisions.
Multivariable, dynamic process model forecasts plant behavior over a defined prediction horizon, enabling proactive and constraint-aware control.
Dual-layer optimization for economic objectives and control moves, delivering tighter regulation and higher yield with minimal energy use.
Closed-loop system identification with PRBS excitation enables engineers to verify and fine-tune model fidelity during operation, ensuring the APC continues to perform optimally under changing process conditions.
Technology Core
- Close-loop, multivariable identification with automatic model grading (A–D).
- 3-term control move optimization for better response speed and robustness than traditional 2-term DMC.
- Progressive deployment, controllers commissioned MV-by-MV as models mature.
- Disturbance modeling for proactive compensation and rejection.
