In early October, 2013, Willy Wojsznis, Mark Nixon and I were notified by the ISA Publications Department that we were the recipients of the “Raymond D. Molloy Award”. The book we co-authored, Advanced Control Foundation: Tools, Techniques, and Applications, sold the most units of any new book published by ISA in 2012. The publication award’s …

When developing a PLS models for quality parameter prediction, the deviation of measurement values from their mean must be shifted in time to account for the time required for a change in the input to impact the quality parameter. Similarly, these delays should be taken into account in the processing of the deviation values used …

One of the key objectives of a process control system is to maintain product quality parameters within specification. On-line analyzers that automatically provide measurements of material properties to the control system may be too expensive, may have proven to be unreliable, or simply may not be available because of the complexity of the sampling system …
