Abstract: The invention relates to a method and a device for controlling the production of a mixture of components, especially a mixture with premix dead volumes.The method and the device according to the invention ensure multivariable regulation feedback by a dynamic observer providing an estimate in real time of the properties of the components of the mixture, said estimate being sufficient to guarantee the effectiveness of the feedback loop. Thus, the desired properties of the mixture are guaranteed despite large uncertainties in the properties of the components on the one hand, and partial knowledge of the mixing process on the other.

Abstract: The invention relates to a method and a system for controlling the production of a mixture of constituents, especially a mixture with premix dead volumes.By correcting the matrices for calculating the mixture constituents, used in calculating recipes, by introducing limit, order relationship and equality constraints, it is possible to avoid the drifts observed in certain special cases by the implementation of the method and to improve, on the one hand, the diagnostic assistance and the control of the estimation of the properties so as to limit the deviations from the actual quality of the constituents of the mixture and, on the other hand, the speed of manufacture of the mixture and the robustness of the method.The method and the system according to the invention ensure multivariable regulation feedback by a dynamic observer providing an estimate in real time of the properties of the constituents of the mixture, said estimate being sufficient to guarantee the effectiveness of the feedback loop.
