Online Seminar Series for IFAC TC 1.2 Adaptive & Learning Systems

The main objectives of our "Online Seminar Series for IFAC TC 1.2 Adaptive & Learning Systems" are:

• Promote the latest research results in the field of Adaptive and Learning Systems;
• Create a forum for high-quality discussion of both theoretical and practical perspectives;
• Reach and engage the researchers and practitioners in our community worldwide;
• Provide a platform for the young generation to network with the rest of the world.

Organization of the Seminar Series:

We plan to run the online seminar series on a monthly basis. We will invite speakers at different career stages, both within and outside of the TC, to share their research with the community. To encourage and train the young generation, e.g., PhD students. We will also organise special events within the seminars series to provide a venue for them to share and discuss their research with their peers and experts in the community.

The seminar will be open to all researchers and practitioners across the world. It will be scheduled at a suitable time (in the afternoon, UTC time) to maximise the possible attendance. The lectures will be recorded and hosted on IFAC YouTube Channel (upon the permissions of the speakers and approval of IFAC).

Details of Next Seminar

The next webinar in this series will be given by Professor Romeo Ortega, Instituto Tecnológico Autónomo de México.

Title: New Robust Parameter Estimators and Systems Reparameterizations: Dealing with Lack of Excitation and Nonlinear Parameterizations
Time: September 26, 2023 (11am CDT, 4pm UTC)

Abstract: In this talk we present some recent results on (i) robust parameter estimation without persistent excitation (PE) and (ii) new reparameterizations of nonlinearly parameterized (NLP) systems. After discussing the motivation to relax the PE assumption, we show how the recently introduced dynamic regressor extension and mixing estimator achieves this objective. Moreover, it allows us to consider, separable, NLP that satisfy an easily verifiable monotonizability property and improves, in a quantitative way, the transient performance of the estimator. In the second part of the talk we discuss some new techniques to deal with the highly complicated---but, alas, often encountered in applications---non-separable NLP. We concentrate our attention on the case of NLP of the form $e^{\theta_i h_i(t)}$, which is very common in physical systems. In the third part of the talk, we show that for nonlinear dissipative systems it is possible to derive an alternative parameterization, which is much simpler than the one usually derived directly from the system dynamic equations. Finally, we present some challenges in adaptive systems theory and survey some new theoretical results aimed at solving them.

We will open the meeting 15 minutes earlier. The participants must join earlier - 10 minutes before the start. It will take some time to let them all in :-)

All of you are welcome! See you there!
