A Framework to Design Controllers for Engineering Applications of Transverse Jets

We propose a hypothetical framework to develop control strategies to optimize the mixing characteristics associated with the actively driven jet in crossflow. This framework is a three-step design procedure. As a first step, we form a preliminary controller with a feed-forward loop in order to develop controllers able to compensate for the dynamics of actuators and sensors. As a second step, we augment the feed-forward loop with a feedback loop in order to develop a plant controller based on a hierarchy of reduced-order models. As a final step, we remove the feed-forward loop and concentrate on the robustness of the plant controller with respect to unmodeled and unpredictable uncertainties.
