This Friday, 29 Oct., I have presented my recent research on Parameter Estimation with Enhanced Performance and obtained the Habilitation à diriger des recherches degree!

We have just finished a project on building modeling with my students from sentraleSupelec, campus Rennes.

The RC model describes the temperature dynamics in two rooms in the CentraleSupelec’s building at Rennes; it incorporates historical weather data and model occupants’ presence. The model is open-access and can be used as a testbed for temperature regulation problems. The project description is available here, and the model is available at GitLab here.

Our recent paper “Switched Observer Design For a Class of Locally Unobservable Time-Varying Systems” has been accepted to Automatica!

As for some recent papers, this research is motivated by a robotics application where the measurements are biased. We show that such a bias in the studied nonlinear systems compromised the system’s observability for some values of input signals. We formulate the problem as observer design for a time-varying locally unobservable system and propose a solution in the class of switched observers. The design is performed via LMIs, and the design is implemented in an experiment.

Our recent paper on “Robust adaptive stabilization by delay under state parametric uncertainty and measurement bias” has been accepted for publication in TAC!

This research is motivated by a nonlinear pendulum control problem. We consider a class of nonlinear systems with biased measurements, unknown parameters, and external disturbances. We avoid a dynamic state reconstruction (synthesis of an observer) using delayed values of the output in the feedback and adaptation laws. The efficacy of the developed control is demonstrated on this application through simulations and experiments.

The first virtual European Control Conference has just finished, and it was an amazing experience! All sessions running in parallel in Zoom rooms with live youtube translations.

Many thanks to the organizers.
