The objective of advanced control projects is to improve the performance of product quality control, while adhering to operating constraints. This is typically done with two technologies, Model Predictive Control to drive the process closer to operating targets and Inferential Measurement to increase the frequency of product quality feedback information. ABB provides this capability in two packages, Predict & Control and Inferential Modeling Platform
Predict & Control is a multivariable, model predictive control (MPC) software technology package. Predict & Control (P&C) is typically implemented at the supervisory control level to manipulate setpoints of multiple control loops in order to drive multiple process output variables to their targets and enforce operating constraints. The P&C software suite includes on-line components for control and operator interaction and off-line components for controller configuration, dynamic model identification, tuning and analysis. The controller operates through existing instrumentation and control equipment so there is no major investment or interruption of production required.
