Title: Rotational Stabilization of Cylinder Wakes Using Linear Feedback Control

Abstract: We demonstrate the feasibility of linear feedback control to stabilize vortex shedding behind twin cylinders using the cylinder rotations. Our approach is to linearize the flow about a desired steady-state flow, use interpolation-based model reduction on the resulting linear model to generate a low-dimensional model of the input-output system with input-independent error bounds, then use this reduced model to design the feedback control law. Closed-loop simulations of the Navier-Stokes equations demonstrate the effectiveness of this control strategy.
