  2. 1. Control and estimation of wall bounded flow systems

    Author : Jerome Hoepffner; KTH; []
    Keywords : ;

    Abstract : This thesis focuses on the application of linear feedback control and estimation to channel flow. Both the initial stage of the transition and the low Reynolds number turbulent cases are studied. From sensors at the wall, the state of the flow is estimated, using a stochastic description of the flow disturbances. READ MORE

  4. 2. Stability and control of shear flows subject to stochastic excitations

    Author : Jérôme Hoepffner; Dan Henningson; John Burns; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control; estimation; stochastic excitations; feedback; model reduction; Fluid mechanics; Strömningsmekanik;

    Abstract : In this thesis, we adapt and apply methods from linear control theory to shear flows. The challenge of this task is to build a linear dynamic system that models the evolution of the flow, using the Navier--Stokes equations, then to define sensors and actuators, that can sense the flow state and affect its evolution.
