- Title
Admittance Identification from Point-wise Sound Pressure Measurements Using Reduced-order Modelling.
- Authors
Volkwein, S.
- Abstract
In this work an acoustic application is studied. The goal is to estimate the complex-valued admittance from given point measurements of the sound pressure. This parameter identification problem is formulated in terms of an infinite-dimensional optimization problem. First- and second-order optimality conditions are discussed. For the numerical realization a reduced-order model based on proper orthogonal decomposition is used. Numerical examples illustrate the efficiency of the proposed approach.
