We develop an approach to subspace system identification using multiple data records and present a simple rank-based test for the adequacy of these data for fitting the unique linear, noise-free, dynamic model of prescribed state-vector, input-vector and output-vector dimensions. The approach is motivated by the prospect of sorting through archives of operational data and extracting a sequence of not-necessarily-contiguous data records individually incapable of providing identifiability but collectively making this possible. The test of identifiability then becomes the sorting criterion for accepting or rejecting new data records. En passant, the familiar Hankel structure of the data matrices of subspace system identification is reinterpreted and revised.
Bio: Bob Bitmead occupies the Cymer Corporation Endowed Chair in Mechanical & Aerospace Engineering at the University of California, San Diego. He holds degrees in Applied Mathematics and Electrical Engineering from Sydney University and Newcastle University, both in Australia. He is a control theorist with a long experience in control applications in many industrial sectors: sugar, steel, mining, telecommunications, aerospace, transportation, energy, and photolithography. His theoretical work is strongly informed and guided by these applications. He was the recipient of the 2014 ASME Rufus Oldenburger Medal, a lifetime achievement award in control. Bob is Vice-President for Financial Activities of the IEEE Control Systems Society. He held many positions on IEEE awards committees. He was a member of IFAC Council from 1996 to 2002. Bob brews his own beer and is an accredited and active Australian Rules Football umpire.
