Software Monitors Model Predictive Controls

Metso ExperTune PlantTriage now performs continuous assessments of the performance of model predictive controls (MPC). Over 100 performance assessments allow a high degree of specificity in the recommended corrective actions. New metrics include effective controller on-time, controller health, time at constraints, model prediction error and oscillation detection.

Version 12 presents the results in a user-friendly browser interface. The interface is completely integrated with Metso ExperTune PlantTriage's traditional monitoring of underlying regulatory control loops, allowing users to drill down directly from MPC monitoring to find root causes that may lie outside the MPC structure itself.
