Abstract

The objective of the present study is to build a reliable model of the dynamics among the chemical modules in the outlet of raw meal grinding systems and the proportion of the raw materials. The process model is constituted from three transfer functions, each one containing five independent parameters. The computations are performed using a full year industrial data by constructing a specific algorithm. The results indicate high parameters uncertainty due to the large number of disturbances during the raw mill operation. The model developed can feed with inputs advanced automatic control implementations, in order a robust controller to be achieved, able to attenuate the disturbances affecting the raw meal quality.
