This article presents the development of the mathematical model and simulation of the process of multiple effect evaporation. This process is used for obtaining sugar or etanol from sugar cane. Development of the balances of mass and energy are the bases for the dynamic non lineal model. The model was developed in the virtual environment EcosimPro, which,(More)
Wiener models consist of a linear dynamic element followed by a static non linear element. This paper shows a non linear model predictive control (NMPC) based on a piecewise linear; the Wiener model is applied on an experimental control of pH. The static nonlinear element of the Wiener model is approximated using piecewise linear function. Identification(More)
