Robust process model in the model-based control techniques identification method and system

摘要

PROBLEM TO BE SOLVED: To provide a method and system for process model identification that enables generation of an acceptable parametric process model even in situations where no process model parameter convergence has been obtained.;SOLUTION: A robust method of creating process models for use in controller generation, such as in MPC controller generation, adds noise to the process data collected and used in the model generation process. In particular, a robust method of creating a parametric process model first collects process outputs on the basis of known test input signals or sequences, adds random noise to the collected process data and then uses a standard or known technique to determine a process model from the collected process data.;COPYRIGHT: (C)2014,JPO&INPIT
