Shah, Sirish L. - University of Alberta - Department of Chemical and Materials Engineering

个人简介

Dr. Shah's research interests lie in the broad area of advanced process control algorithms and methods for monitoring process and controller performance. Specifically, the focus of Dr. Shah's more recent research activity has been in the area of multivariate statistical analysis of plant data for control loop performance assessment, process monitoring, fault diagnosis, and development of new control-relevant identification algorithms for use in the design of model-based predictive controllers.He is a past winner of the D.G. Fisher award of the CSChE for significant contributions in the Systems and Control area, as well as the NSERC University-Industry Synergy Award.
