Proactively identify control loop performance issues and systematically isolate the associated root-causes.
Control Station’s PlantESP is a the leading control loop performance monitoring (CLPM) solution. It detects production-related controlissues and facilitates plant-wide process optimization. It enables process manufacturers to improve operational efficiency and to avoid the high costs of unplanned downtime by equipping users with actionable intelligence.
A well-established statistical analysis method that makes it easy to determines the lead-lag relationship existing between two or more PID control loops. Cross Correlation is an essential tool for determining the root-cause of controller performance issues, saving significant time and effort for operators of complex production environments.
Apply PlantESP’s OCE metric to benchmark performance at loop, unit, and plant levels. Leverage each score to better understand current performance and to track the impact of your site’s process improvement initiatives.
The Overall Controller Effectiveness (OCE) metric, introduced in PlantESP 25.1, evaluates real-world control loop performance at both loop and unit levels. Unlike traditional metrics that assess behavior in isolation, OCE delivers a composite score based on three factors: percent time in normal mode, percent of data within an acceptable error band (“good error”), and percent time not constrained.
