State-space predictive control of two liquid tanks system with constraints of process variables

Abstract

This paper presents a method called the predictive control used to control a nonlinear process about a selected operating point. The system of the two funnel liquid tanks in series is chosen as an exemplar process. The parameters of the tanks simulate a large industry tanks used in a chemical industry. The state-space CARIMA mathematical model is used for the output values prediction. This paper describes the linearization process of the nonlinear system at the operating point and a possibility of constraints of the process variables. The designed controller is verified on the process without and with a time-delay. © ECMS Thorsten Claus, Frank Herrmann, Michael Manitz, Oliver Rose (Editors).
