Abstract

We introduce an asymptotic method (ASYM) of identification. The ASYM has been developed for multivariable process identification for model based control. Fundamental problems, such as test signal design for control, model order/structure selection, parameter estimation and model error quantification, are solved in a systematic manner. The method can supply not only an input/output model and an unmeasured disturbance model which are (asymptotic) maximum likelihood estimates, but also the upper bound matrix for the model errors that can be used for model validation and robustness analysis. An application of the method for a crude unit atmospheric column DMC is presented
