    Controller Design for Active Closed-Loop Control of Cavity Flows
    (2004) Van,P.; Debiasi,M.; Yuan,X.; Caraballo,E.; Efe,M.Ö.; Ozbay,H.; Malone,J.
    In this paper we discuss feedback controller design issues for active control of shallow cavity flows. Linear controllers, such as H ∞, PID, and Smith predictor based controllers are designed and tested experimentally. The ineffectiveness of using fixed linear models in the design of linear controllers for the cavity flows is demonstrated via experimental results. In order to better address this problem, we are in the process of developing a nonlinear model of the cavity flow dynamics using Proper Orthogonal Decomposition (POD). We briefly discuss control issues related to the class of feedback systems involving this type of nonlinear plants.
