Abstract

Closed-loop systems have been developed for controlling the flow above a three-dimensional turret. The top of the turret is hemispherical, houses a flat optical aperture, and can rotate about two axes (pitch and yaw). The extent of separation and concomitant turbulence levels in the flow above the aperture change as the turret rotates. Suction jet slots circumscribing the aperture serve as control input; an array of pressure sensors on the turret surface provides the controller with information about the state of the flow above the surface. The control objective is to minimize the separation and turbulence in the dynamic environment created by the articulating turret. The closed-loop control systems include dynamical and measurement-based estimators, regulators, filters, and compensators. These components are developed using both computational and experimental data, and the control systems are evaluated through a series of control-in-the-loop CFD simulations and wind tunnel runs. Controller designs and computational tests are described in "Feedback Flow Control for a Pitching Turret (Part I), and the follow-on wind tunnel tests are described here.
