15th IFAC Symposium on Automatic Control in Aerospace took place
in Italy, Bologna/ Forli at September 2-7, 2001. The Symposium was organized
and sponsored by International Federation on Automatic Control –Technical Committee on Aerospace.
The great merit at the Symposium organization and conducting belongs to the Chairman of the International Program Committee and the National Organizing Committee prof. Gianni Bertoni (Italy). The Symposium was held at the University of Bologna that is situated in Bologna and airport of Forli.
The Symposium Welcome Ceremony took place at
the Sala dello Zodiaco at the Palazzo della Provincia. The plenary sessions were reserved for well
known international speakers, who were invited to present a state of the field.
The first plenary paper was made by well know Italian scientist A. Isidori
“Internal-Model-Based Control of Nonlinear Systems”. The paper was devoted to
the problem of having the output of the
system to asymptotically track prescribed trajectories and/or to asymptotically
reject undesired disturbances, in the presence of possibly large model
uncertainties. The paper reviewed the most recent advances in this area and
outlined its potential interest in aero-space control.
The plenary paper of K. Schiling (Germany)
“Space Robotics for Interplanetary Missions” concerned to advanced exploration
missions to the other planets of our solar system. The conversation was about
the control aspects of the specific European interplanetary missions like
HUYGENS (part of Cassini) to Saturn / Titan, ROSETTA to a comet and also
planetary rovers for surface exploration.
Richard van Holtz (ESA) presented the plenary
paper “Operations Control Processes for the Galileo Satellite Navigation Services”.
The very interesting plenary paper was
presented by Mark T. Balas (USA) “Adaptive Control of Aerospace structure with
Persistent Disturbances”. The author made the review recent work in direct
adaptive control and disturbance cancellation with application to precision optical
structures.
At the Symposium the special some sessions were
organized at Forli Campus.
As the special plenary paper at that sessions
prof. Gianni Bertoni presented the paper “Presentation of Forli Laboratory on
Satellite-based Navigation”.
At the plenary paper “Methods and Soft Ware for
Research and Design of Spacecraft Robust Fault Tolerant Control Systems” Y.
Somov (Russia) made brief analytic overview on advanced method for the fault
detection, isolation, diagnosis and onboard reconfiguration.
Y. Bar-Shalon (USA) presented the plenary paper
“Tracking and Surveillance Systems”. The conversation was about the evolution
of the technology of tracking objects of interest (targets) in a cluttered
environment using remote sensors. Applications were presented from Air Traffic
Control (data fusion from 5 FAA radars for 800 targets) and underwater surveillance
for a LO target.
At the Symposium there were organized 9
sessions of special interests.
On the Session 1 “Spacecraft Attitude Control
and Space Robotics” some interesting papers were presented. The attention was
displayed to the papers of S.D.
Zemlyakov, V.M. Glumov (Russia) “Autonomous Predicted Control of Spacecraft
with Changing Configuration” and V.Yu. Rutkovsky, V.M. Sukhanov “Some Questions of Safety and Efficiency Control
of a Space Robotic Module’s Flight Near by a Space Station”. At the both papers
the conversation was about a special free-flying space robotic module during
its flight near by a Space Station.
The paper of M.M. Quottrup, R. Wisniewski, T.
Krogh-Sorensen (Denmark) “Passivity Based Nonlinear Attitude Control of the
Romer Satellite” was devoted to the Danish Romer satellite. A novel momentum
distribution algorithm for reaction wheels was proposed.
On the Session 2 “Theory and Applications on Guidance, Navigation and Control of
Aerospace Vehicles” the paper by L.K. Kuzmina (Russia) “Stability Theory
Methods in Girostabilization Systems
Dynamics” could be specially marked. The paper was devoted to the specific problems of the mathematical
modeling for the systems of stabilization and orientation with gyroscopic
controlling elements. At the paper on the base of Lyapunov’s method it was proposed the special reduction
principle, solving the decomposition problem for such systems.
On the Session 4 “Satellite Navigation Systems,
GRS / GLONASS Applications” the paper
of M.Crisci, L.Daga, A. Mirri, S. Mazzoni (Italy) “A Virtual Laboratory on
Satellite-Based Navigation” could be marked. The Virtual Laboratory has been
developed on the faculty of Engineering of the Bologna University to simulate
the on board avionics of a general aviation aircraft. At the paper the authors
described details about the configuration and architecture of this laboratory.
The great interest at the Symposium was displayed to invited Session 8
“Advances in Missile Guidance and Control Systems”. Especially two papers of A.
Tsourdos, B.A.White “Modern Missile Flight Control design: an Overview” and
“Modern Missile Guidance design: an Overview” “ attracted the audience’s
attention for a long time.
I could like to add that prof. Gianni Bertoni
as the Chairman of National Organizing Committee and Alba de Giovanni as the Secretary of the Committee were able
to create so cordial situation that every participant of the Symposium had the feeling that just he or
she was a main person of the Symposium.
Once more moment: preprints of full papers of
the Symposium were perfectly printed.
At the Symposium there were more than 10 participants from Russia. So preprints
of the Symposium are enough accessible. For information: L.K.Kuzmina (Lyudmila.Kuzmina@ksu.ru Kazan,
Russia), Y.Somov (pnms@sstu.samara.ru
Samara, Russia), Nebylov (nebylov@aanet.ru
Saint-Petersburg, Russia), S.D.Zemlyakov (zeml@ipu.rssi.ru
