| Abstract: |
A system and method for providing raw mix proportioning control in a cement plant with a fuzzy logic supervisory controller. A raw mix proportioning controller determines the correct mix and composition of raw materials to be transported to a mixer. The raw mix proportioning controller uses the fuzzy logic supervisory controller to determine the proper mix and composition of raw materials. The fuzzy logic supervisory controller takes targeted set points and the chemical composition of the raw material as inputs and generates the proportions of the raw material to be provided as an output for the next time step.

What is claimed is:
1. A system for providing raw mix proportioning control in a cement plant, comprising:
- a plurality of raw material;
- a plurality of transport belts for transporting the plurality of raw material;
- a measuring device that measures the composition of the plurality of raw material transported by the plurality of transport belts;
- a raw mix proportioning controller, coupled to the plurality of transport belts and the measuring device, for controlling the proportions of the plurality of raw material transported along the plurality of transport belts, wherein the raw mix proportioning controller comprises a fuzzy logic supervisory controller that uses a plurality of target set points and the composition of the plurality of raw material as inputs and generates a control action to each of the plurality of transport belts that is representative of the proportions of the material to be transported along the belts the fuzzy logic supervisory controller comprising a plurality of low level controllers, wherein each low level controller receives a change in a target set point as an input and generates a change in a control action as an output; and
- a mixer, coupled to the plurality of transport belts, for mixing the proportions of each of the plurality of raw material transported therefrom.
