DESCRIPTION:The first published work on closed-loop control of anesthesia a
 uthored by Mayo\, Bickford and Faulconer dates back to 1950. However\, fee
 dback\ncontrol of anesthesia has yet to become adopted for clinical use de
 spite the fact that since 1950\, and especially since the availability of 
 depth-ofhypnosis\nmonitors many systems have been developed and clinically
  tested. For clinical adoption to take place\, benefits to the patient hav
 e to be\ndemonstrated while patient safety has to be guaranteed. This pres
 entation will focus on the engineering design process that can ensure pati
 ent safety\nby design. A major characteristic of the anesthesia closed-loo
 p control problem is the significant inter and intra-patient variability a
 nd that under such\ncircumstances\, the control system has to perform adeq
 uately and safely for a patient it has never seen and with very limited le
 arning opportunity.\nThis is why it is crucial for such systems to be desi
 gned by expert control engineers well versed in robust control theory. I w
 ill briefly describe the\ntheory of robust control and demonstrate its use
  for closed-loop anesthesia in order to guarantee closed-loop stability an
 d a minimum level of performance\nacceptable to the clinician. Furthermore
 \, the system has to be able to handle safely a number of exceptions with 
 well-designed fallback\nmodes. This is where the field of safety-preservin
 g control\, a concept developed for aeronautic applications\, can provide 
 a number of attractive\nsolutions. This will be demonstrated through work 
 performed at the University of British Columbia when developing our closed
 -loop TIVA control\nsystem\, iControl. Finally\, because the anesthesiolog
 ist will remain in the loop and has to be able to take over in a safe mann
 er should the need arise\,\nthe Human-Computer Interaction (HCI) aspects h
