| Abstract: |
A system and method for tuning a raw mix proportioning controller used in a cement plant. A fuzzy logic supervisory controller tracks the performance of a cement plant simulator to target set points for attaining a correct mix and composition of raw materials. A genetic algorithm adjusts the fuzzy logic supervisory controller's performance by adjusting its parameters in a sequential order of significance.

What is claimed is:
1. A system for tuning a raw mix proportioning controller, comprising:
- a plurality of target set points;
- a cement plant simulator for simulating the operation of a cement plant according to a plurality of set points;
- a fuzzy logic supervisory controller for controlling the operation of the cement plant simulator in accordance with the plurality of target set points, wherein the fuzzy logic supervisory controller tracks error and change in tracking error between the plurality of set points of the cement plant simulator and the plurality of target set points and provides a control action to the cement plant simulator that minimizes the tracking error; and
- a tuner, coupled to the cement plant simulator and the fuzzy logic supervisory controller, for optimizing the tracking between the cement plant simulator and the plurality of target set points.
