Joint IFAC/IEEE CSS webinar series

The main objectives of the webinar series are to bring forward IFAC values on open science in automatic control, to reach nonlinear control researchers and practitioners in all parts of the world and to promote the latest research activities in the field of nonlinear control systems worldwide. The works to be presented are usually based on the latest achievements reported in journal papers but have not been presented at conferences.


The next webinar in this series will be given by Prof. Kirsten Morris, University of Waterloo, Canada.

Date: 10:00 am EDT / 3:00 pm Central Europe /11:00 pm Japan Time on Thursday, March 14.

The recorded session will be made available in the IFAC youtube channel:

Title: Systems theory for partial differential-algebraic equations

Abstract: There are a number of applications which are modelled by partial differential-algebraic equations (PDAEs). One of practical importance is the electro-chemical model for lithium-ion cells. This model can be converted to a (nonlinear) PDE. This is not possible, or practical, in all cases. Establishing existence and uniqueness of the solutions to these equations, as well as continuous dependence on data is non-trivial. For linear systems, a decomposition of the state-space that leads to an extension of the Hille-Yosida Theorem is described. For dissipative partial differential equations the Lumer-Phillips generation theorem characterizes solvability and also boundedness of the associated dynamics. An extension of the Lumer-Phillips generation theorem to linear dissipative differential-algebraic equations is given. Examples of controller design strategies for these systems are also discussed.

The webinar is organized by Claudia Califano (vice-chair education of IFAC TC 2.3), Bayu Jayawardhana (vice-chair publication of IFAC TC 2.3), Hiroshi Ito (chair of IFAC TC 2.3 Non-linear Control Systems) and Andrea Serrani (chair of IEEE TC Nonlinear Systems and Control).
