Report of the IEEE CSS TC on CACSD

From: Didier Henrion <henrion@laas.fr>, Chair
Date: 27 October 2009

Here is a summary of the activities of the TC
during the second semester of 2009.

*** Restructuring the TC on CACSD ***

Fabrizio Dabbene (Politecnico di Torino, Italy) will take over
as a Chair of the TC on CACSD following the MSC 2010 in Japan.
It is expected that Fabrizio works in close collaboration
with Graziano Chesi (Univ. Hong Kong), who is now chairing
the TC on SU (systems with uncertainty).

*** Software ***

Vasile Sima informed me that the Subroutine Library for Control Theory
(SLICOT) has been updated for being distributed under a GNU General Public License.
The routine for L-infinity norm computation has been improved mainly
by calling the HAPACK-based SLICOT codes for computing the eigenvalues of
Hamiltonian matrices.  Work is in progress for implementing
structure-exploiting eigensolvers for skew-Hamiltonian/Hamiltonian
matrix pencils.

*** Next meeting ***

Fabrizio Dabbene and Graziano Chesi are planning a joint meeting of
the CACSD and SU TCs during the IEEE CDC in Shanghai in December 2009.
