The article titled “Empirical Reduced-Order Modeling for Boundary Feedback Flow Control” [1] was found to contain material from the following published article: Seddik M. Djouadi, R. C. Camphouse, J. H. Myatt: Reduced order models for boundary feedback flow control. American Control Conference, 2008. 11–13 June 2008. Date Added to IEEE Xplore: 05 August 2008. DOI: 10.1109/ACC.2008.4587119.

This was not cited due to an oversight. The JCSE article expands on the ACC 08 publication by 30%, including a new section on controller design. In Section , Problem Geometry, the authors added several expressions (18) to (22), with explanations. The Introduction is organized differently and contains a paragraph addressing the issue of closed loop model reduction. There are more explanations and Figure in Section , Controller Design. In Section , Application to the Galerkin Model, the authors added more explanation with expressions (61) and (63).
