BOTERO CASTRO, HÉCTOR ANTONIO  y  ALVAREZ ZAPATA, HERNÁN DARÍO. A REVISION OF THE MOST FREQUENT METHODS FOR STATE ESTIMATION IN CHEMICAL PROCESSES. Dyna rev.fac.nac.minas [online]. 2009, vol.76, n.158, pp.135-146. ISSN 0012-7353.

This paper shows a literature review of some proposed methods for state estimation in chemical processes industry. The revision is made for estimators of fixed sampling time. The analysis is done considering the types of estimators, the types of models used by the estimators, the reported applications for those estimators, the advantages and the limitations of estimators use. Finally, a real problem of state estimation in an industrial process is exposed.

Palabras clave : State estimator; State observer; Kalman filter; Nonlinear system.
