Research in Efficient Predictive Control and Integrated Microchemical Systems

Back
Abstract:
In this talk, I will present an overview of my research program at Lehigh University by focusing on two research topics: (1) Nonlinear Model Predictive Control; (2) Integrated Microchemical Systems. In the first part of the talk, I will present our results on the development a computationally efficient scheduled output feedback Model Predictive Control (MPC) algorithm for constrained nonlinear systems with large operating regions. This involves the design of a set of local output feedback predictive controllers with their estimated regions of stability covering the desired operating region, and subsequent implementation as a single scheduled/switched output feedback MPC which achieves nonlinear transitions with guaranteed stability. The algorithm combines the desirable features of gain-scheduling and model predictive control to efficiently control nonlinear systems. In the second part of the talk, I will provide an overview of several on-going research projects on microreactors and microchemical systems in my group.Microchemical systems are a new generation of miniature chemical systems that carry out chemical reactions and separations in precisely fabricated three dimensional microreactor configurations in the size range of a few microns to a few hundred microns. Typical microchemical systems combine fluid handling and reaction capabilities with electronic sensing and actuation, are fabricated using integrated circuit (IC) manufacturing techniques and use silicon and related IC industry materials, polymers,ceramics, glass or quartz as their material of construction. I will present our work on MEMS-based microfabrication, modeling and control of microreformers for hydrogen delivery systems in micro-fuel cells.

Biographical Sketch:
Mayuresh V. Kothare is currently an Associate Professor of Chemical Engineering at Lehigh University and co-director of the Chemical Process Modeling and Control Research Center. He received his B.Tech. in Chemical Engineering (1991) from the Indian Institute of Technology, Bombay; M.S. (1995) and Ph.D. (1997)both in Chemical Engineering from the California Institute of Technology. From 1995-1996, he was a research assistant at ETH and has been a visiting scholar at City College New York (Jan-June 1997) and Purdue University (June 1996). He joined the Chemical Engineering Department at Lehigh in July 1998 after a one year postdoctoral appointment with Mobil Oil Corporation. He is recipient of the Ted Peterson Student Paper Award from the CAST division of the AIChE, the ACS Petroleum Research Fund young investigator grant and the CAREER award for young investigators from the US National Science Foundation. In recognition of his research at Lehigh, he was appointed a P. C. Rossin Assistant Professor (2001-2003) and a Frank Hook Assistant Professor (2002-2003) and received the Alfred Nobel Robinson Award (2002) "for outstanding contributions in service of the university and unusual promise of professional accomplishments". In 2002, he was recognized as an outstanding reviewer of Automatica. He is an Associate Editor of the IEEE Transactions on Automatic Control and the IEEE Control Systems Society's Conference Editorial Board.
