Tel Aviv University Hello everyone, The next colloquium talk will be held on Monday, 14/5/2012, 12:15, Schreiber 006, Tel Aviv University. The speaker is Arie Levant (Tel Aviv University) and the title of his talk is Advanced Mathematical Black-Box Control The abstract is given below. Tea and coffee at 12:00, same room. Hope to see you there. For information about future colloqiua, see <http://www.math.tau.ac.il/~klartagb/colloq_2011.html> You are all welcome to suggest colloquium speakers for this semester. Yours, Bo'az -------------- Abstract: Control theory deals with processes depending on an input parameter called control. The real-time information on the process is provided by an output, as a result of "measurements". The control task is to adjust the control input in time, so as to provide for needed process features. The standard approach is to build a mathematical model of the process and to develop a corresponding feedback control. Unfortunately, it often happens in practice that no reliable model is available. The question arises whether it is possible to treat a system as a "black box", avoiding any dependence on the model. In that way not only parameters of the model are considered uncertain, but the very nature of the model is uncertain. A method proposed in this talk mathematically establishes such approach. Practical relative degree notion is introduced. Universal controllers corresponding to each degree are developed to make the output track signals given in real time. Computer simulation and recent practical results of in-vivo blood glucose concentration control demonstrate the feasibility of the suggested approach. --------------------------------------------------------- Technion Math Net-2 (TECHMATH2) Editor: Michael Cwikel <techm@math.technion.ac.il> Announcement from: <klartagb@post.tau.ac.il>
