Title
Model-Based Advanced Control: Perspectives from Academia and Oil & Gas Industry
Abstract: This two-part talk gives an overview of Model-Based Control from Academic and Industrial perspective. The first part of this talk focuses on giving an industrial perspective on Advanced Process Control (APC). While APC techniques have been successfully applied in petrochemical and allied sectors these have found rather modest success in upstream Oil and Gas. Field experiences with using simple logic-based control and static model-based control will be presented. Finally the challenges and opportunities in applying APC solutions in non-traditional industries will be discussed. The second part of this talk will focus on application of Approximate Dynamic Programming (ADP) for control of distributed parameter systems. ADP is a computationally feasible method for online optimal control of process systems. The aim of ADP is to develop a "Value Function" (also called "cost-to-go function") that characterises desirability of the system state with respect to the objective function. Use of ADP for large dimensional state-space is challenging due to "curse of dimensionality" -- a term used to indicate exponential growth in computational requirement with increasing state dimension. Model reduction techniques are used to reduce the state dimension. Both model-based and model-free ADP is demonstrated.About the Speaker: Dr. Niket Kaisare completed his B.Chem.Engg from UDCT (currently ICT-Mumbai) and PhD from Georgia Institute of Technology both in Chemical Engineering. During his PhD he worked on Model Predictive Control and Approximate Dynamic Programming. He spent two years at University of Delaware doing his post-doc in multi scale modelling and catalytic combustion. He was an assistant professor at IIT-Madras for four years from July 2007 - 2011 where he currently holds an adjunct position. He was awarded IIT-M Young Faculty Recognition Award for Research and Teaching in 2010 and INAE Young Engineer Award in 2011. He is currently a Principal Scientist at ABB Corporate Research Center in Bangalore working in Control and Optimization. His research interest include model-based control optimisation fuel processing unconventional oil and gas and catalysis.
