Advantages of OKID-ERA Identification in Control Systems. An Application to the Tennessee Eastman Plant

Abstract

Data-driven OKID-ERA identification of the open-loop Tennessee Eastman plant is performed to obtain a linear model for control design purposes. Analysis such as numerical conditioning, output response errors, and zero-pole mappings highlight some definite advantages of the OKID-ERA approach when compared with models derived from typical linearization techniques. The plant under study is a recognized benchmark in the field of plant-wide control systems.
