Abstract : This document is a final report for ONR grant N00014-89-J-3018, 'Demonstration Study of Hierarchical Control of Fluid-Dynamic Phenomena.' Our overall objective was to develop a laboratory experiment wherein the performance of a fluid dynamic process would be effectively controlled using a model-based system controller. We considered, as a sample fluid-dynamic process, the flow over a high-lift circulation-control wing. The essence of our model-based approach was a progression of fluid-dynamic models corresponding to the expected range of complexity in the attached and separated flow of the experiment. Development of the demonstration involved both fabrication and testing of the high-lift wing model and test apparatus, as well as coding and evaluation of the control algorithms and fluid-dynamic models. preparatory to this development, a flow facility in which to conduct the experiments had to be designed and constructed. Unfortunately, due to delays in completion of this facility, the demonstration experiments could not be carried out within the budget of the grant. Our overall objective was therefore not met, however, we will report here on the substantial progress we did make to establish the capabilities cited above.
