State Space Models for Aeroelastic and Viscoelastic Systems.
Abstract
We develop state space models for aeroelastic systems including unsteady aerodynamics. We establish the applicability of semigroup theory for these systems on weighted product spaces by showing well-posedness and obtaining a dissipative estimate for the infinitesimal generator of the associated Cauchy problem. Numerical techniques are developed for the singular neutral functional differential equation that model the aeroelastic systems. Also, we present a technique based on quasilinearization for identifying unknown coefficients in parabolic partial differential equations. This technique is applied to both linear and nonlinear equations with spatially varying unknown coefficients.
