Laboratoire des Signaux et Systèmes is a major French public research laboratory based in Gif-sur-Yvette affiliated with Université Paris-Saclay, the Centre National de la Recherche Scientifique, and CentraleSupélec. The laboratory focuses on signal processing, control theory, and systems engineering with applications spanning communications, robotics, and energy systems, engaging with institutions such as École Polytechnique, Université Paris-Sud, and industrial partners including Thales Group and Schneider Electric. Its researchers publish in venues connected to IEEE, ACM, and collaborate on projects funded by the European Research Council, Agence nationale de la recherche, and multinational consortia like Horizon 2020.

History

The laboratory traces origins to research units formed during the post-war expansion of French science linked to CNRS reorganizations and the development of the Plateau de Saclay research cluster, interacting with establishments such as École Normale Supérieure and Institut d'Optique. Over decades the unit evolved through mergers influenced by national initiatives like the creation of Université Paris-Saclay and institutional reforms involving CentraleSupélec and Paris-Sud University. Major milestones include participation in European projects under frameworks like FP6 and FP7, and contributions to national programs with agencies such as CEA and INRIA. The laboratory's historical trajectory intersects with broader French research policies exemplified by partnerships with Ministère de l'Enseignement supérieur, de la Recherche et de l'Innovation and collaborations with companies such as Airbus and Alstom.

Organization and Structure

The laboratory is organized into thematic teams and administrative units coordinated with partner institutions including Université Paris-Saclay and CentraleSupélec, with governance models reflecting practices at CNRS research units and academic departments like those at École Polytechnique. Leadership comprises directors, deputy directors, and scientific councils drawn from member organizations including Thales Group and representatives from funding bodies like ANR. Internal structure includes research teams aligned with international structures such as those found in IEEE Signal Processing Society and IFAC communities, with doctoral schools coordinated with EDSP (École Doctorale de Paris-Saclay) and postdoctoral programs linked to institutes such as Collège de France.

Research Areas

Research integrates signal processing, control systems, and applied mathematics with applications in communications, robotics, power systems, and biomedical engineering, aligning with topics central to IEEE Transactions on Signal Processing, Automatica, and conferences like ICASSP and IFAC World Congress. Domains include statistical signal processing tied to methods from Kalman filter theory and optimization linked to algorithms in convex optimization and techniques pioneered in workshops associated with INRIA. Work covers robotics connected to CNES satellite systems and autonomous vehicles engaging with standards from ETSI, and energy systems research related to RTE (Réseau de Transport d'Électricité) and smart grid initiatives collaborating with Schneider Electric and EDF. Biomedical signal studies intersect with institutions such as Inserm and projects in neuroengineering connected to NeuroSpin facilities.

Facilities and Laboratories

Facilities include experimental platforms for antenna arrays and wireless testbeds comparable to those at CEA-Leti and electromagnetic measurement labs akin to setups at Thales Alenia Space, dedicated control hardware-in-the-loop benches similar to those found in Laboratoire de l'Intégration du Matériau au Système (LIMS), and robotics halls equipped with motion capture and manipulators like systems used at LAAS-CNRS. The site hosts cleanrooms, Fourier optics benches, and high-performance computing clusters interoperable with national infrastructures such as PRACE and regional centers like IDRIS, alongside specialized instrumentation for power electronics and microelectronics comparable to facilities at STMicroelectronics research centers.

Education and Training

The laboratory contributes to graduate education through master's and doctoral supervision within Université Paris-Saclay doctoral schools, joint degree programs with CentraleSupélec and coursework linked to École Polytechnique, organizing seminars and winter schools in partnership with societies such as IEEE and SIAM. It provides internships and postdoctoral fellowships supported by grants from European Research Council and national scholarships from CNRS and Ministère de l'Enseignement supérieur, de la Recherche et de l'Innovation, and hosts summer schools and MOOCs in collaboration with platforms associated with Sorbonne Université and professional training linked to Institut Mines-Télécom.

Collaborations and Partnerships

Collaborative networks involve European institutions like Technical University of Munich, Imperial College London, and Politecnico di Milano, industrial partnerships with Thales Group, Schneider Electric, Airbus, and public agencies such as CNES and EDF. The laboratory participates in consortiums funded by Horizon 2020 and bilateral programs with institutions like MIT and ETH Zurich, and engages in standardization efforts with bodies such as ETSI and collaborations with national research infrastructures including RENATER.

Notable Projects and Contributions

Notable projects include development of algorithms for large-scale signal reconstruction with links to advances in compressed sensing discussed in venues like IEEE Transactions on Information Theory, control strategies for microgrids contributing to initiatives with RTE and EDF, and robotics control algorithms applied in aerospace projects with Airbus and CNES. The laboratory's contributions extend to open-source software releases used by communities surrounding Scipy, TensorFlow, and toolboxes disseminated through collaborations with INRIA and datasets shared with research infrastructures like DataVerse-style repositories, influencing standards and practices cited in publications and adopted by partners including Thales Group and Schneider Electric.
