ESTIMATION OF BOUNDED PHYSICAL PARAMETERS

A method for the constrained estimation of the physical system parameters of linear systems from measured data is described which uses a two-stage procedure: step response estimation via the frequency-sampled filter approach followed by a non-quadratic bounded optimisation to obtain the physical parameters. The method is illustrated using simulated data and evaluated using experimental data.
