DESCRIPTION:Frequency domain subspace identification is an effective means
  of obtaining a low order dynamic model from frequency domain data. With n
 oisy data several problems arise in choosing the appropriate rank and find
 ing the low order representation. A nuclear norm (sum of the singular valu
 es) minimisation based method\, using spectral constraints\, is described 
 and shown to be an effective technique for overcoming these problems. \n\n
 Bio:\n\nRoy Smith is a Professor in the Automatic Control Laboratory at th
 e Swiss Federal Institute of Technology (ETH\, Zurich) in Switzerland. Fro
 m 1990 to 2010 he was on the faculty of the Electrical Engineering Dept. a
 t the University of California\, Santa Barbara. He received his undergradu
 ate education at Canterbury University in New Zealand (1980) and a Ph.D. f
 rom the California Institute of Technology (1990).  \n\nRoy Smith's resear
 ch interests include: the identification and control of uncertain systems\
 , and distributed estimation\, communication and control systems. His appl
 ication experience includes: process control\, automotive engines\, flexib
 le space structures\, aeromanoeuvring Mars entry vehicles\, formation flyi
 ng of spacecraft\, magnetically levitated bearings\, high energy accelerat
 or control\, and energy control for buildings. He has been a long time con
 sultant to the NASA Jet Propulsion Laboratory on guidance\, navigation and
  control aspects of interplanetary and deep space science spacecraft. He i
 s a Fellow of the IEEE\, an Associate Fellow of the AIAA\, and a member of
  SIAM and NZAC.
