The last decade has seen the development of a number of approaches for estimating those variables which are difficult to measure on‐line in industrial process situations. Whilst a range of techniques is available, a common element is the use of pro

Inferential estimation and control are techniques tailored for processes with severe sampling limitations on key process measurements. Often such systems have complex, time-varying dynamics making sustainable control performance an elusive target. As

Principal components analysis (PCA) is a standard statistical technique, which is frequently employed in the analysis of large highly correlated data sets. As it stands, PCA is a linear technique which can limit its relevance to the non-linear system

The inherent complexities of the extrusion process have made the development of both mechanistic and parametric models problematic. This contribution addresses the issues involved in developing a realistic model of an industrial reactive plasticating

Viscosity Index, an important measure of the quality of lubricant oil, is difficult to measure on-line. As such, it is only available at infrequent intervals from laboratory analysis resulting in large and variable measurement delays. The problem can

This paper presents an industrial case study examining the application of inferential estimation to a lubricant production plant. Three estimation algorithms are studied. First, an existing plant inference model is compared to a static estimator desi

Process intensification has the potential to change the state of the chemical and process industries. The polymer film compact heat exchanger (PFCHE) is a new type of intensified heat exchanger. The potential market is seen as being large [1] but as

Novel distillation control configurations are studied in this paper. In these configurations, composition manipulators are functions of the reflux flow rate, the vapour boil up rate, and the top and bottom product flow rates. Parameters in these func
