Abstract	In this paper we present a method for developing control--oriented reduced--order models of wake flows based on solutions of the steady Euler equations. Such reduced--order models are constructed as potential flow solutions generalizing the point--vortex F\"oppl system and reproduce the velocity field of the steady solutions of the Euler equations obtained by Elcrat et al.~(2000). Various properties of such higher--order F\"oppl systems relevant from the control--theoretic point of view are analyzed and compared to the properties of the classical F\"oppl system and the steady Euler equations.
