Abstract
A system for on line inference and control of physical and chemical properties of polypropylene and its copolymers is described. The system comprises models for the inference of physical and chemical properties that are not continuously measured and relevant models to control these properties as well as production rate, density of the reaction medium and other process variables of interest. The described control system allows to maximize production rate as well as catalyst yield in the producing process.
