Abstract

The authors consider parameter estimation problems in structures with piezoceramic actuators and sensors. The problems are discussed in the context of a variational formulation of damped second order partial differential equations with unbounded input coefficients. Approximation techniques are introduced and numerical results of parameter estimation are given. Experimental data are used to test the computational results
