System and method for providing raw mix proportioning control in a cement plant with a gradient-based predictive controller

摘要

A system and method for providing raw mix proportioning control in a cement plant with a gradient-based predictive 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 a gradient-based predictive controller to determine the proper mix and composition of raw materials. The gradient- based predictive 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. The output is generated by using a non-linear constrained optimization.
