Controller performance monitoring

Integration of CPM with diagnosis was reported for single-loop cases 

---

When a failure occurs during operation, the cause can be attributed not only to the process equipment, or the sensor network but also to the controller. Controller performance monitoring (CPM), considered as a subset of plantwide process monitoring and diagnosis activities, deserves a separate discussion. Thus, Chapter 9 provides an overview of controller performance monitoring tools and offers a case study to illustrate the key concepts. 

Controller performance monitoring (CPM) ensures proper performance of the control systems for safe and profitable operation of a process and man-...
