Control of subsonic cavity flows by neural networks-analytical models and experimental validation
Efe, M. Ö.; Debiasi, M.; Yan, P.; Özbay, Hitay; Samimy, M. (American Institute of Aeronautics and Astronautics, 2005)Flow control is attracting an increasing attention of researchers from a wide spectrum of specialties because of its interdisciplinary nature and the associated challenges. One of the main goals of The Collaborative Center ... -
Infinite dimensional and reduced order observers for Burgers equation
Efe, M. Ö.; Özbay, Hitay; Samimy, M. (Taylor & Francis, 2005)Obtaining a representative model in feedback control system design problems is a key step and is generally a challenge. For spatially continuous systems, it becomes more difficult as the dynamics is infinite dimensional ... -
Integral action based Dirichlet boundary control of Burgers equation
Efe, M. Ö.; Özbay, Hitay (IEEE, 2003)Modeling and boundary control for Burgers Equation is studied in this paper. Modeling has been done via processing of numerical observations through singular value decomposition with Galerkin projection. This results in a ... -
Low dimensional modelling and Dirichlét boundary controller design for Burgers equation
Efe, M. Ö.; Özbay, Hitay (Taylor & Francis, 2004)Modelling and boundary control for the Burgers equation is studied in this paper. Modelling has been done via processing of numerical observations through proper orthogonal decomposition (POD) with Galerkin projection. ... -
Multi input dynamical modeling of heat flow with uncertain diffusivity parameter
Efe, M. Ö.; Özbay, Hitay (Taylor & Francis, 2003)This paper focuses on the multi-input dynamical modeling of one-dimensional heat conduction process with uncertainty on thermal diffusivity parameter. Singular value decomposition is used to extract the most significant ... -
Neural network-based modelling of subsonic cavity flows
Efe, M. Ö.; Debiasi, M.; Yan, P.; Özbay, Hitay; Samimy, M. (Taylor & Francis, 2008)A fundamental problem in the applications involved with aerodynamic flows is the difficulty in finding a suitable dynamical model containing the most significant information pertaining to the physical system. Especially ... -
Proper orthogonal decomposition for reduced order modeling: 2D heat flow
Efe, M. Ö.; Özbay, Hitay (IEEE, 2003-06)Modeling issues of infinite dimensional systems is studied in this paper. Although the modeling problem has been solved to some extent, use of decomposition techniques still pose several difficulties. A prime one of this ... -
Seven tuning schemes for an ADALINE model to predict floor pressures in a subsonic cavity flow
Efe, M. Ö.; Debiasi, M.; Yan, P.; Özbay, Hitay; Samimy, M. (Sage Publications Ltd., 2009)This paper presents a simple yet effective one-step-ahead predictor based on an adaptive linear element (ADALINE). Several tuning schemes are studied to see whether the obtained model is consistent. The process under ... -
Support vector networks for prediction of floor pressures in shallow cavity flows
Efe, M. Ö.; Debiasi, M.; Yan, P.; Özbay, Hitay; Samimy, M. (IEEE, 2007)During the last decade, Support Vector Machines (SVM) have proved to be very successful tools for classification and regression problems. The representational performance of this type of networks is studied on a cavity ...
