A Simple Approach to Industrial Soft Sensor Development and Deployment for Closed-Loop Control

This study provides a comprehensive approach to effectively deploy end-to-end soft sensors in live industrial settings. The approach provides process-industry specific steps for data pre-processing, algorithm selection, and deployment. This study is concluded with three industrial examples of soft sensors deployed for three applications. Each soft sensor was deployed either directly into the distributed control system (DCS) or as an application running on a dedicated workstation and communicate to the DCS via OPC, for closed-loop control.
