System identification

System Identification, essentially data driven modelling,  involves the creation of mathematical models of dynamic systems using measurements of their inputs and outputs, while relying on a bare minimum of a-priori assumptions.  My group focuses on developing methods for identifying nonlinear systems, in applications ranging from neuromuscular control and robotics  to chemical process control and electric power systems.

Optimization

System Identification often boils down to minimizing the errors between the outputs of unknown system and the of model, resulting in an optimization problem.  As a result, I have developed efficient techniques for solving several system identification related optimization problems.


Biography

David T. Westwick the BASc degree in engineering physics from The University of British Columbia (1986), and the MScE and PhD degrees in electrical engineering from The University of New Brunswick (1988) and McGill University (1995), respectively.  His doctorate was followed by postdoctoral fellowships in the Department of Biomedical Engineering at Boston University, and the Systems and Control Engineering Group at Delft University of Technology. Since 1999, he has been a faculty member in the Department of Electrical and Computer Engineering at the Schulich School of Engineering, where he is currently holds the position of Professor and Department Head.  He has held appointments as a Visiting Scholar at the Department of Fundamental Electricity and Instrumentation (ELEC) at the Vrije Universiteit Brussel, and at the Sensory Motor Performance Lab at the Rehabilitation Institute of Chicago/Northwestern University.  His publications include over 150 papers in peer-reviewed journals and international conferences, as well as the book “Identification of Nonlinear Physiological Systems” (2003) published by John Wiley and Sons as part of the IEEE Engineering in Medicine and Biology Society book series.
