Issues in Control of Particle Size Distribution

Back
Abstract:
Our ongoing research concerns the development of model-based control systems for chemical processes described by population balance equations. This class of models describes systems that possess population distributions (such as size, morphology, molecular weight, etc.), and exhibit dynamic behavior arising from their distributed nature. These distributions typically characterize important end use metrics, including adhesiveness, rheological, and optical properties. Nonlinear optimization approaches to controlling the particle size distribution will be reviewed, emphasizing trajectory generation, objective function sensitivity and multi-objective formulations.Specific applications that will be addressed in this talk include granulation and semi-batch emulsion polymerization processes.

Biographical Sketch:
Dr. FRANCIS J. DOYLE III is a Professor in the Dept. of Chemical Engineering at the University of Delaware. He received his B.S.E. from Princeton (1985), C.P.G.S. from Cambridge (1986), and Ph.D. from Caltech (1991), all in Chemical Engineering. After graduate school, he worked at DuPont as a Visiting Scientist in the Strategic Process Technology Group (1991-1992), then held Assistant/Associate Professer positions at Purdue University. He moved to the University of Delaware in 1997 and was promoted to Full Professor in 2001. His research interests are in process modeling and control with applications to polymerization systems, pulp and paper processes. In addition, he has an active research program in systems biology. He is the recipient of several research awards (NSF NYI (1992), ONR Young Investigator (1996)) as well as teaching awards (Purdue Potter Award - Engineering Teaching Award (1995), ASEE Section Outstanding Teacher Award (1996), Tau Beta Pi Teaching Award (1996)). In 1998, he was elected as a Fellow of the Institute for Transforming Undergraduate Education (ITUE) at the U. of Delaware, and was elected an academic trustee of CACHE in 1999. He is presently a Humboldt Fellow and visiting faculty member at Stuttgart University.
