- Robust control of a MIMO thermal-hidraulic process with Sensor compensation in real time Virgilio López Morales René Valdes Aslain Ingeniería Process modeling Sensor compensation Linearized observer Brunovsky canonical transformation The main goal of this paper is twofold: To show a kind of robustness in a nonlinear multivariable (NL MIMO) systemwith feedback control, by employing some linearization and observation techniques well known in reference kindof model; and at the same time it is a proposal to immunize the measurements of a level capacitance-based sensorwhen there are changes in the measured variables properties, by employing an on-line compensation. The MIMOthermal-hydraulic nonlinear system is stabilized when some linearizing conditions are met and a designmethodology for using a state feedback scheme is established. In order to assign poles to the control system, theJacobian linearization is transformed to the controllable canonical form. This is accomplished by the Brunovskysimilarity transformation, and by a static state feedback. A Luenberger observer is added to the control system inorder to improve its stability. Illustrations of these techniques are shown via numerical and practical simulationscarried out directly in the inexpensive physical process. 2005 artículo científico 1665-6423 https://www.redalyc.org/articulo.oa?id=47401103 en http://www.redalyc.org/revista.oa?id=474 Journal of Applied Research and Technology application/pdf Universidad Nacional Autónoma de México Journal of Applied Research and Technology (México) Num.1 Vol.1
