In the present study, a hierarchy of control-oriented reduced order models (ROMs) for fluid flows is presented. Control design requires simplicity, accuracy and robustness from an online capable Galerkin model. These requirements imply low order of the associated dynamical system. Standard POD (praper orthogonal decomposition) Galerkin models may provide a low-dimensional representation of a given reference state. Yet, their narrow dynamic range and lack of robustness pose a challenge for control design. We propose key enablers to increase the dynamic range of the POD model. An 11-dimensional hybrid model is discussed which includes, in addition to 8 POD modes, a shift mode to resolve base-flow variations, and a complex global stability mod...
