[PDF] COAL MILL MODELLING USING EVOLUTIONARY

2021-2-14  The paper presents the development of a mathematical coal mill model using evolutionary computation techniques and its on-line implementation. A modified version of the coal mill model is described in the first part of the paper, which is a further study to the mill model developed in the authors’ previous work. The model is then converted into a discrete-time form for the purpose of on-line
