Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding

Abstract

A new method is presented to estimate the parameters of two models commonly used in the process industry. The method is based on the method of moments for a general input signal. It consists of a level change in closed loop and if needed an open loop step experiment.
