SUMMARY:Feedback Control and the Arrow of Time - Professor Malcolm Smith (
 Cambridge University Engineering Department)
DTSTART:20080530T100000Z
DTEND:20080530T110000Z
UID:TALK12245@talks.cam.ac.uk
CONTACT:Dr Guy-Bart Stan
DESCRIPTION:The talk reports on recent joint work with Tryphon Georgiou on
  the central role that the time asymmetry of stability plays in feedback c
 ontrol.  It is shown that this provides a new perspective on the use of do
 ubly-infinite or semi-infinite time axes for signal spaces in control theo
 ry. The talk goes on to explain the implications of this time asymmetry in
  modeling uncertainty\, regulation and robust control.  We point out that 
 modeling uncertainty and the ease of control depend critically on the dire
 ction of time. We also discuss the relationship of this control-based time
 -arrow with the well known arrows of time in physics.\n\n
