Abstract:
1. A device for producing and controlling production of a mixture M of n components, the device comprising: transport channels for transporting the components to be mixed into a main channel connected to a place for receiving the mixture M; flow rate regulators for controlling the rate of flow of the components in each transport channel; in-line analysers located in the main channel for continuously measuring representative parameters of the mixture M being produced; a non-transitory readable memory configured to store: a computer-implemented calculating program configured to calculate proportions u of the components involved in the mixture; and a computer-implemented estimating program for estimating the properties of the components using the measurements of the properties of the mixture that are measured by the in-line analysers, and the computer-implemented calculating program calculates the proportions u of the components involved in the mixture using the estimate so as to obtain a mixture having predetermined properties y; and wherein the computer-implemented estimating program is configured to implement the following operations: (i) at time t=0: (ii) at time t′=t+Δt: properties of the components; and a processor configured to execute the computer-implemented calculating program and the computer-implemented estimating program stored in the memory to produce and control the production of the mixture M.
