✦ Synopsis

This paper considers optimal control problems constrained by coupled hyperbolic and parabolic-like dynamics arising in an acoustic structure interaction. A numerical algorithm, based on the FEM, is formulated for computations of solutions to associated matrix algebraic Riccati equations. The developed LQR theory is extended to a disturbance rejection problem where the disturbance can be L2 (O,z;L2(Fo)) or L2(0 , ~ ;L2(Fo)). Results of a numerical simulation of the algorithm are presented.
