  • radiation pressure mediated control of an optomechanical cavity
    Physical Review A, 2018
    Co-Authors: J Cripe, N Aggarwal, R Singh, Robert Lanza, A Libson, Garrett D Cole, D E Mcclelland, N Mavalvala, T R Corbitt
    Abstract:

    We describe and demonstrate a method to control a detuned movable-mirror Fabry-Perot cavity using radiation pressure in the presence of a strong optical spring. At frequencies below the optical spring resonance, self-locking of the cavity is achieved intrinsically by the optomechanical (OM) interaction between the cavity field and the movable end mirror. The OM interaction results in a high rigidity and reduced susceptibility of the mirror to external forces. However, due to a finite delay time in the cavity, this enhanced rigidity is accompanied by an anti-damping force, which destabilizes the cavity. The cavity is stabilized by applying external feedback in a frequency band around the optical spring resonance. The error signal is sensed in the amplitude quadrature of the transmitted beam with a photodetector. An amplitude modulator in the Input Path to the cavity modulates the light intensity to provide the stabilizing radiation pressure force.

  • Integral sliding mode control of an extended Heisenberg system
    IET Control Theory & Applications, 2009
    Co-Authors: Michael Defoort, Thierry Floquet, Wilfrid Perruquetti, Sergey V. Drakunov
    Abstract:

    This study deals with the practical robust stabilisation and tracking problems of the perturbed multidimensional Heisenberg system with some additional integrators in the control Input Path. This objective is achieved by the use of variable structure control laws with an integral augmented sliding variable. This note shows how to select the integral sliding surface in such a way that the practical stabilisation of the extended Heisenberg system is achieved in spite of the uncertainties and without loss of controllability. Experimental results on a wheeled mobile robot show the performance of the proposed controller for the practical stabilisation and tracking problems.

  • Sliding mode control of extended heisenberg systems
    IFAC Proceedings Volumes, 2004
    Co-Authors: Thierry Floquet, Sergey V. Drakunov, Wilfrid Perruquetti
    Abstract:

    Abstract This paper is dedicated to the stabilization of the Heisenberg system with some additional integrators in the Input Path. This objective is achieved by the use of sliding mode control laws: the first one is based on the classical theory and requires the perturbations to be matching while the second one involves higher order sliding mode theory and is robust to a larger class of disturbances. Some simulations illustrate the given results.
