Adaptive reduced-order controllers for a thermal flow system using proper orthogonal decomposition (English)
0 references
The author considers the flow control problem. A method to obtain a reducer-order model is given by using an optimal set of basic functions associated with Galerkin projection. An initial set of data, obtained from numerical simulations, is updated during the optimization process. No convergence proof is given. A minimization of vorticity for Navier-Stokes equations is performed using the boundary temperature as control mechanism. The sequential quadratic programming method and quadratic programming method are used. Interesting numerical results are presented in the last part for channel flows.
