At Euler building
Organized by Mathematical Engineering
Speaker :
Ljubisa Miskovic (Ecole Polytechnique Fédérale de Lausanne, Suisse/CESAME)
Abstract :
In this talk, the identifiability of closed loop systems is re-examined
with a double objective: (i) clarify the differences between already existing
definitions of identifiability and propose one that is both realistic and workable;
(ii) establish conditions on the controller and on the external excitation that guarantee
identifiability in the case of multi-input multi-output (MIMO) systems. Furthermore, the
following question is addressed: is it necessary that all reference inputs be excited in a MIMO
system if a certain accuracy level is desired for the parameter covariance matrix?
