Abstract

This survey paper presents a discussion and comparison of various numerical techniques used for process identification. Among the methods discussed are identification by *- numerical deconvolution *- auto-correlation and cross-correlation *- spectral density *- sinusoidal response measurement *- learning models *- Wiener theory of nonlinear systems *- differential approximation *- gradient techniques *- quasilinearization *- invariant imbedding The purpose of this report is to introduce the principle of some of these different methods and compare the result of their application to simple problems.
