Preface
TheInternationalConferenceon Control and EstimationofDistributed Parameter
Systemstookplacefrom July14-20, 1996, attheBildungshausChorherrenstiftVorau
in Vorau (Austria). It was the seventh in a series ofconferences that begun in 1982.
51 researchers from 11 states contributed to draw a broad and diverse picture of
the recent developments in optimal control and parameter identification of partial
differential equations, both from a theoretical and numerical viewpoint. We thank
them all for their contributions to an enjoyable and interesting conference.
We address our thanks to the whole staff of the Bildungshaus Chorherrenstift
Vorau. The pleasant atmosphere at the Bildungshaus has been a key ingredient to
the success ofthe meeting and the stimulating interaction between the participants.
We are particularly indebted to Mrs. L. ReiB, who helped us omnipresently with all
the everyday issues ofa conference like this one.
This meeting was facilitated by funding from the following organizations:
Amt der Steiermiirkischen Landesregierung,
Bundesministerium fUr Wissenschaft und Verkehr,
Christian Doppler Laboratorium fiir Parameter Identifikation
und Inverse Probleme,
European Research Office ofthe U.S. Army,
Spezialforschungsbereich F003 "Optimierung und Kontrolle",
Stadt Graz,
U.S. Air Force European Office ofAerospace Research and Development.
It is our pleasure to acknowledge the generous support by these institutions.
Once again, the friendly and supportive team of Birkhiiuser, in particular
Dr. T. Hintermann and Mrs. S. Lotrovsky, have provided an optimal opportunity
to publish our proceedings. Our special thanks go to Mrs. G. Krois. Herenthusiasm,
skillandworkpower havebeenthe backboneoftheorganizationoftheconferenceand
the preparation ofthe 'lEX manuscript ofthe proceedings you are presently reading.

1. Introduction
Weconsiderthefollowing classofabstract nonlineardamped parameterdependent
hyperbolic systems evolving in a complex separable Hilbert space H:
(1.1) Wtt +AI(q)w+A2(q)wt +N*g(q)(Nw) = f(t; q)
(1.2) w(O) = 'Po
(1.3) Wt(O) = 'Pl'
Here AI(q),A2(q) are unbounded operators depending on some parameter q, g(q) is
a parameter dependent nonlinear operator in H, N is an unbounded operator, and
f is a parameter dependent forcing term. Precise conditions on these operators are
given below.
This class of systems was introduced in [BGS, BLMYj and further studied in
[BLGMY] as a model for the behavior of nonlinear elastomers. These materials,
which are used in the development of active and passive vibration devices, are rub
ber or polymer based composites that involve complex viscoelastic materials. Their
behaviorcannot be adequately modelled using the theory oflinearelasticity. Indeed,
they exhibit nonlinearities in material and geometric properties so that there is a
nonlinear relationship between stress and strain even for small strains. We illustrate
with a simple example that takes into account these nonlinearities, and describe the
associated general parameter estimation problems. (For detailed discussions of this
and other models see [BLMY, BGS, BLGMY, B1].)
