In control and system theory the system Gramian matrices of linear input-output systems have wide-spread use. Empirical Gramian matrices correspond to the system Gramians for linear systems, but extend to parametric and nonlinear systems due to a data-driven computation. The empirical Gramian framework is an open-source Matlab toolbox, enabling the computation of the following empirical system Gramians: - Empirical Controllability Gramian - Empirical Observability Gramian - Empirical Cross Gramian - Empirical Linear Cross Gramian - Empirical Sensitivity Gramian - Empirical Identifiability Gramian - Empirical Joint Gramian and a wrapper frontend for: - Model reduction (POD, Modified POD, DSPMR, Balanced POD) - Parameter identification and parameter reduction - Combined state and parameter reduction - Decentralized control - State and parameter sensitivity analysis - Nonlinearity quantification - Uncertainty quantification - Gramian indices (ie for Optimal actuator and sensor placement) - Approximate system norms and system indices - Tau functions For more information see: https://gramian.de ------------------------------------------------------- From: Maria Grazia Russo [log in to unmask] Date: May 01, 2020 Subject: POSTPONED, FAATNA20, Italy As a consequence of the COVID-19 emergency, on the behalf of the Organizing Committee I announce that we are forced to postpone the conference FAATNA20 (http://web.unibas.it/faatna20/index.html) until the next year, precisely to the period 6-9 July, 2021. We will leave all aspects of the current organisation unchanged.
