【Abstract】 It is difficult to establish accurate and practice mathematical models of the process of grinding and classification due to their complicated mechanism and many factors affecting them. In view of these facts, the authors conducted the computer simulation of grinding and classification using a new control algorithm, which adopts such functions as prediction, feedback and rectification of DMC on the basis of fuzzy control, because the former has better adaptability to a complicated system, especially the slowly time varying parameter and large time delay system.更多还原
