Second call for benchmark examples:
-----------------------------------
The Working Group on Software WGS, which consists of a number of
experts in control theory, numerical analysis and software design
from Belgian, Dutch, English and German Universities, Research Institutes
and Industry, develops in cooperation with the Numerical Algorithms Group NAG
from Oxford a Subroutine Library In COntrol Theory, called SLICOT.
The original goal of the SLICOT endeavor is the realization of a portable
library of basic, high-quality routines for systems and control theory and
signal processing, particularly with respect to numerical reliability
and computational efficiency. The current release 2.0 includes about 90
user callable FORTRAN 77 routines, mainly for the analysis, synthesis and
design of linear time-invariant control systems.
Since numerical robustness and efficiency are the basic requirements for all
contributions to future releases, the group is
looking for good benchmark examples for the evaluation and testing
of numerical algorithms in this area. We are particularly interested
in examples which represent ill-conditioned problems and examples
which test the limits of the numerical methods with respect to
parameters like accuracy and speed.
Special areas of interest are the following:
Reduction to state space forms, minimal realization
Filtering problems
Riccati, Sylvester and Lyapunov equations
Pole placement problems
identification problems
variable coefficient problems
descriptor systems in control
robust control problems
adaptive control
Since our first call for benchmarks we have collected the following
examples:
a) A test model data set for helicopter vibration:

plants : a benchmark problem.
c) H-2, H-infinity control and model reduction:

and its treatment as a multibody system.
Report TUM-M9204 Techn. Univ. Muenchen, 1992

Linear Algebra and its Applications, Vol. 137/138 , 1990 , pp. 39--66.
We would be very happy to receive further test problems and benchmark
examples.
Examples in form of FORTRAN subroutines, MATLAB m-files or hardcopy papers
are welcome. They should contain values for all used parameters, as well as
a reference solution for which the accuracy is known.
The benchmark examples should be sent to

Summary:
A frequent problem in engineering is the control of a critical system,
where it is necessary to maintain the output within strictly defined
bounds so that the system can operate effectively. This book is devoted
to critical control systems, and shows how Zakian's method of inequalities
is ideal for their design.
Several classes of critical control system are covered, including analogue
systems in both the time and frequency domains, discrete time systems, and
sampled-data systems. Some analytical solutions for the solution of the
design problem are given.
A numerical method for solving the problem using the method of inequalities
is described, and the numerical algorithm is presented. Several other useful
algorithms have been developed for use with the method of inequalities, and
these are also detailed.
Examples and detailed case studies are included and illustrate how the theory
can be applied to practical control system design.
Practising control engineers in many fields of industry, and academic and
industrial researchers will find this book useful.

NEURAL NETWORKS IN TELECOMMUNICATIONS
Neural Networks in Telecommunications
edited by Ben Yuhas, Bellcore, Morristown, NJ and Nirwan Ansari,
New Jersey Institute of Technology, Newark, NJ
Neural Networks in Telecommunications provides an overview of a
wide range of telecommunications tasks being addressed
with neural networks. These tasks range from the design and control
of the underlying transport network to the filtering,
interpretation and manipulation of the transported media. The
chapters focus on specific applications, describe specific
solutions and demonstrate the benefits that neural networks can
provide. By doing this, the authors demonstrate that neural
networks should be another tool in the telecommunications engineers
toolbox, offering unique solutions to problems in
telecommunications.
For engineers and managers in telecommunications, Neural Networks
in Telecommunications provides a single point of access
to the work being done by leading researchers in this field, and
furnishes an in-depth description of neural network
applications.

Summary:
69 researchers, from 9 countries, gathered in Santa Barbara
(June 18--20th, 1992) for this workshop. The organizers
were Mohammed Dahleh, John Doyle, and Roy Smith
and sponsorship was provided by the NSF and AFOSR.
The motivation for the workshop was the difficulty experienced
in obtaining models of uncertain systems for robust control
design. This has hindered the more widespread application
of robust control design techniques. Attendees typically had
research experience in either traditional identification or
robust control. In each area, some progress has been made
towards the common goal of developing a unified identification
and design paradigm. The workshop (and this volume) focused
on: set membership identification; confidence interval models;
identification in a worst case setting; and the properties
and application of iterative identification/design schemes.
Participants were invited to submit papers to this volume in
either or both of two categories: speculative essays and
formal papers. The essays are intended to provide an overview
of the area and outline future research directions. The papers,
on the other hand, give a concrete indication of where the
field currently stands. Both the essays and the papers were
written after the workshop, giving the authors an opportunity
to present their ideas and work in the context of the wider
issues. The nature and extent of the work is best summarized
in the table of contents reproduced below.

INFORMATION THEORY AND COMMUNICATIONS
RESEARCH OPPORTUNITIES AT THE
US ARMY RESEARCH LABORATORY
Research opportunities described below are available on the campus of
the US Army Research Laboratory at Aberdeen Proving Ground, Maryland.
We are interested in extending a few appointments for one year to recent
awardees of the PhD and one to a senior research associate, typically a
faculty member on sabbatical leave.
Robust Networking
Work on a variety of problems in information theory and communication
theory is required for effective battlefield information distribution.
Non-Gaussian channels are used with behaviors that are often difficult
to predict. Bandwidth is more of a limitation than nodal processing
power, and channel sharing is the paradigm. Research problems include:
(1) better protocols for the random access channel in a spread spectrum
(frequency hopping or direct sequence) environment, (2) coding and signal
processing for the most general channel models possible, (3) multivariate
algebraic methods for error control, and (4) soft decision decoding
techniques for improved iterated codes.
The foregoing is descriptive of our interests, and we will consider
proposals for work on a wide variety of information theoretic and
communications problems. For further information, please contact:
