  • 10h00 : High order sliding mode (HOSM) observation and identification - Leonid Fridman
    
    Résumé :
    The short overview of high order sliding mode control algorithms is given.Two new observation HOSM finite time convergent strategies are suggested:• hierarchical strategy based on super twisting algorithm allowing to reconstruct the system state without differentiation;• high order sliding mode differentiation for the systems with arbitrary relative degree with respect to the output injections.The identification algorithms basing on the finite time convergence are suggested.For identification of perturbation the filtered version of equivalent control is used. For parameter identification the least square method allows to reconstruct system parameters via filtered version of equivalent control.
