Summarized by Eveline Gottzein


The "IFAC Technical Committee on Automatic Control in Aerospace" was founded in 1963.
Scientists of the first hours were J.A. Aseltine, (USA) Boris Naumov (USSR), Lars Monrad-Krohn
(Norway), Walter Haeussermann (USA), Jim Nevins (USA), Dan DeBra (USA) and Bob Fishell
(USA) and Alexander M. Letov (USSR), Boris Zypkin (USSR), and Boris N. Petrov (USSR).

The Space/Aerospace TC grew out of the Application TC. J.A. Aseltine, from 1963 -1966
Chairman of the Theory Committee became the first Chairman of the “Technical Committee on
Automatic Control in Space”. The first Symposium on Automatic Control in Space was organized
in June 1965 by the Norwegian Host Society in Stavanger, Norway, Title: “First IFAC
Symposium on Automatic Control in the Peaceful Uses of Space”. To top off the high
quality technical sessions there were social events and a great dinner party. In the spirit of the
time, the representative of the Norwegian host held a dinner speech on "Aerospace and
Elephants as seen from the different IFAC nationalities".

Since the beginning, a great number of internationally outstanding scientists and engineers
working in various disciplines of Space/Aerospace Control devoted their time and services to the
IFAC Space/Aerospace Technical Committee.

The agenda of Symposia and topics of workshop reflect over 40 years of development in
Space/Aerospace Vehicle dynamics and controls and the underlying progress in components
like sensors, actuators and computers. We are able now to control complex, powerful, large
flexible and widely autonomous systems to extremely high accuracy. We know much more about
the mathematical models of our systems and components and are using computational tools to
an extend that could become a danger in itself, if we forget to questions over and over again
their validity for our present design work. A number of spectacular failures have given testimony,
that the old rule is still true: “Don’t model what you cannot test and don’t rely on what you cannot
verify”.
The Technical Committee was started as

Workshops:

The sequence of workshops was started in the later seventies by three workshops organized in
a series by John Hursh at Draper Lab in Boston on “System reconfiguration and recovery
from failure”.

The workshops were so successful that in the TC meeting during the last workshop, a decision
was taken to organize workshops on special emerging subjects regularly, preferably every three
years to bridge the gap between IFAC World Congresses and IFAC Aerospace Control
Symposia and give TC members an opportunity to meet at least once a year.

Listed below are workshop subjects over the years and the names of the key promoters and
organizers.

 •   Workshop organized by M. Pelegrin at Sup Aero/CERT in Toulouse in the early eighties on
     the “Space Environment: SEU’s, electrostatic discharge and cosmic radiation”.

 •   Workshop organized by Robert H. Cannon and Dan DeBra at Stanford University in 1983
     on “Simulation and Validation Techniques to establish Spacecraft Control System
     Performance”.

 •    Workshop organized by Glenn E. Cunningham at JPL in Pasadena in 1988 on
     “Spacecraft Autonomy: Present and future Capabilities”.

 •   Workshop organized 1991 by Sherman Seltzer at Control Dynamics in Huntsville, Alabama
     on the “Dynamics and Controls of Flexible Structures: Modelling and Experimental
     Verification”.

 •   Workshop organized at ESOC in Darmstadt by Wolfgang Wimmer and Sunji Manabe in
     1992 on “Spacecraft Automation and On-Board Autonomous Mission Control”.

 •   Workshop organized in Breckenridge at the Beaver Run Resort by L Giulicchi and A.
     Bukley in 2000 on the “Application of GPS in Spacecraft Control”.

 •   Workshop organized in Breckenridge at the Beaver Run Resort by L Giulicchi and A.
     Bukley in 2003 on the “Control of Optical Systems”.

The workshops were a rich source for invited papers to bring one year later attendees of the
symposia up to date on emerging developments.
Attendance at the workshop is usually between 50 and 70 people.

Role in the IFAC Technical Network

The Technical Committee on Automatic Control in Aerospace is not working as a monolithic
block within IFAC but part of the IFAC technical network by co-operating with other technical
committees e.g. through co-sponsoring meetings and contributing invited papers. Examples are
invited sessions on spacecraft systems’ at the Symposia of the TC on Intelligent Autonomous
Systems, on Mechatronic Systems, on Computers and Telematics, as well as on Human-
Machine Interfaces.

The TC on Aerospace Control is supporting IFAC Journals AUTOMATICA and Control
Engineering Practice and affiliated Journal SPACE TECHNOLOGY by submitting and
recommending manuscripts for publication. Representatives of the TC have been supporting the
editorial boards of AUTOMATICA (J. Sasiadek), Control Engineering Practice (K. Schilling and
H. Siguerdidjane) and SPACE TECHNOLOGY (topic editor: K. Schilling, editorial advisors: E.
Gottzein, J. Mitchell, D. DeBra) for many years.


Aerospace TC Guidelines

Guidelines to govern future work and organization of the Aerospace TC were discussed and
unanimously approved by the TC members in 2002. See “Leadership Structure for the IFAC
Technical Committee on Aerospace” in the attachment at the end of this report.

Acknowledgement

Finally, I want to thank all the TC and steering committee members who helped me to collect the
material fort his summary.

I sincerely hope that coming Aerospace TC Chairmen will keep the “IFAC Automatic Control in
Aerospace Technical Committee” lively, on course to provide leadership to aerospace engineers
working in controls, and lead the TC to even greater success and future heights.

I recommend that future Chairmen update this summary for their term of office to have it
complete for the “100 year anniversary of IFAC” in Heidelberg in 2056 and future generations.

                          The Leadership Structure for the
                              IFAC TC on Aerospace
                                 Issue 15.02.2002

Following the standard organizational structures of companies, the IFAC TC on Aerospace
leadership is composed of the
  • Executive committee, which is responsible for the overall TC policy and consists of the
     chair and two vice-chairs
  • Steering committee, consisting of the former TC chairs, supporting with their professional
     expertise and IFAC experience the executive committee

The future executive committee is to be confirmed by the TC based on the proposal of the acting
chair, which is to be agreed with the steering committee. The period of duty is between two
consecutive IFAC World congresses for 3 years. The task distribution is as follows:
        Chair of TC: defines the overall policy, reports on meetings, sends the annual report to
the CC-chair, should attend the workshops and symposia of the TC, organize the World
Congress sessions, nominates TC members in consulting with Vice Chairs and Steering
Committee, organizes TC meetings at least once a year (including writing and distribution of
minutes)
        1st vice-chair: organizer of the symposium in the related 3-years period
        2nd vice-chair: incoming chair, who will chair the TC in the succeeding period; chairs TC
meetings in the absence of the chair.
The executive committee is responsible to the Aerospace TC and IFAC for the proper
conductance/ initiation of all related and required TC activities. The usual means of
communications with and between TC members is by electronic mail. The executive committee
shall inform the TC members on TC activities regularly. A TC meeting should be conducted at
least once a year

The executive committee members perform together
 • Periodical appointment of TC members,
 • Initiation of conferences,
 • Special appointments for TC activities (by example publications, public relations),
 • Suggestions of honorary members,
 • Participation in the World Congress.

This way a good information flow between these three persons on the key TC duties, as well as
continuity in leadership should be achieved. Usually the 3 members should come from different
continents in order to reflect the internationality of IFAC.
The executive committee in coordination with the steering committee decides all matters not
addressed explicitly above.

The steering committee supports the executive committee with their background knowledge on
past activities and TC decisions made, as well as by recommendations on future activities and
on personal for future leadership. They should be informed on the running business by being

placed on the cc-e-mail list of the executive committee. Its members generate the report on “new
directions” to the IFAC TC on Aerospace and provide recommendations on topics for workshops
and for the symposium scope. They should be consulted for suggestions on keen old speakers,
plenary speakers, IPC members, and invited session organizers for the conferences organized
by the TC. The steering committee has responsibility for the quality of conferences organized by
the TC.
