PREDAVANjE prof. dr VIKTORA URUMOVA

U okviru SEENET-MTP mreže (Mreža zemalja Jugoistoc(ne Evrope u oblasti 
teorijske i matematic(ke fizike, http://seenet-mtp.info/), UNESCO 
projekta „Training and Mobility Program; Promotion of exellence and 
growing of the youth’s interest for education in Physics and 
Mathematics“, koji realizuju Fizic(ki fakultet u Krajovi (Rumunija) i 
Prirodno-matematic(ki fakultet u Nišu (Katedra i Centar za teorijsku 
fiziku Prirodno-matematic(kog fakulteta u Nišu), najavljujemo predavanje 
pod nazivom

"TIME-DELAY FEEDBACK CONTROL OF NONLINEAR OSCILLATORS".

Predavac( je prof. dr Viktor Urumov, sa Prirodno-matematic(kog fakulteta 
Univerziteta Sv. C'irilo i Metodije u Skoplju, Makedonija.

Abstract:
In the introductory part several examples of nonlinear oscillators will 
be provided, such as van der Pol, Lorenz and Roessler models, commonly 
present in the current literature related to studies of simple dynamic 
systems with complex behavior. Another well known system of phase 
oscillators analytically solved by Kuramoto undergoes phase transition 
into synchronized state when the strength of coupling between 
oscillators exceeds some critical value.
The main part of the lecture will provide information on recently 
published results on stabilization of unstable fixed points of nonlinear 
oscillators. The stabilization is successful in wider domain and becomes 
more robust when the feedback term of Pyragas type contains varying 
delay. The method is first applied to individual oscillators defined by 
systems of ordinary differential equations and systems described by 
time-delay equations, e.g. the equation of Mackey-Glass, and then to 
systems of coupled nonlinear oscillators introduced to model the 
behavior of neurons.

Predavanje c'e biti održano u sredu, 29. juna 2010. godine od 12:00 
c(asova, u Svec(anoj Sali (prvi sprat) Prirodno-matematic(kog 
fakulteta u Nišu (Višegradska 33).
