It is generally accepted that PID loop health has a direct impact on the plant’s bottom line: it reduces variability, improves quality and throughput, and decreases energy costs and raw material usage. This has been well proven and documented in many articles. An earlier paper (Patwardhan and Ruel, 2008) outlined criteria for determining what can be considered as excellent, good, fair, or poor controller performance. That paper also dealt with roles and responsibilities of key players needed to work toward control performance best practices. This paper completes that earlier discussion by outlining a work process to support the effort.

Note that this white paper was written in collaboration with Chris McNabb.
