Abstract :
Identification of time continuous dynamic systems is necessary since sampled data approximation is not sufficient enough to control the dynamical systems including the nonlinear systems. A method is proposed with some numerical examples for estimation of parameters in linear systems. It is shown that wavelet connection coefficients, used in accurate numerical simulation, can extract enough information concerning derivatives and their products by integration of wavelet transformed signals.
