  • PDF COAL MILL MODELLING USING EVOLUTIONARY

    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
