Equipe SyNeR

SYNER is a research team of the Laboratoire d’Automatique, Génie Informatique et Signal de Lille (LAGIS – UMRS CNRS 8219) which is associated to the National Center of Scientific Research (CNRS), Ecole Centrale Lille and the Université de Lille1.

The mission of the SYNER team is to develop new methods and tools in the areas of Control Engineering and Systems Theory .

The research concentrates on Identification, Estimation and Control of Nonlinear and Time-Delay Systems. A particular attention is given to Robust Control theory, Hybrid systems theory, performance optimization and design principles.

Theoretical research is combined with numerical tools and supported by dedicated laboratory experiments.

Areas of expertise

  • Robust Observation and Control
    • time-delay systems
    • sliding mode control
    • homogeneous systems
    • aperiodic sampling and control
    • control of nonlinear oscillations
    • linear systems with time-varying parameters (LPV)
    • hybrid systems
    • flatness control theory
    • linear matrix inequalities

     

  • Non-Asymptotic estimation (cooperation with the INRIA NON-A project)
    • finite-time observers
    • online numerical differentiation
    • switches estimation in hybrid systems
    • algebraic methods for parameters and delay identification
    • model-free control


Applications

  • Networked/Embedded Control Systems (haptic control, bilateral teleoperation over Internet and Wifi networks)
  • Mobile robots (cooperative path planning, stabilization, coordination,...) and WSAN (Wireless Sensors and Actuators Networks)
  • Electrical actuators (sensorless control of stepper motors, magnetic bearing,...)
