Domainsystem Identification Toolbox for Matlab : a Complex Application

Frequency domain system identiication has been rapidly developing during the past years. The new comprehensive Matlab toolbox is a successful implementation of the methods of the whole identiication procedure. Its core is a maximum likelihood estimate of parametric transfer function models, maybe with a delay, but also ooers help for nonparametric transfer function identiication. It contains tools for excitation signal design, data preprocessing, parameter estimation, model and error presentation, model validation, simulation, archivation and documentation. This paper illustrates the use of many functions of the toolbox on the example of the iden-tiication of a model of a exible robot arm.
