Cement roller press control by fuzzy logic reasoning

The control of cement grinding roller is that the oil-pressure is commanded to follow a desired setting pressure. The original method of determining the setting pressure in terms of driving current is a PI-like method. But by this method, the grinding roller control will result in large fluctuation of pressure and current caused by variation of feedstocks. According to the previous operation
