Additional advances in fuzzy logic temperature control

As rubber and plastics compounds have evolved into very complex formulas and their uses have expanded, the need for more precise temperature control has become necessary. In today´s world of rubber and plastics products, temperature and process control is very critical to the quality, appearance, and consumer acceptance of a manufacturer´s products. This is one of many reasons why the temperature controls or the process controls have advanced from simple ON/OFF controllers to the more advanced microprocessor based controls and why the control algorithm has also changed. The algorithms have gone from just providing proportional control to what is called fuzzy logic control. At this point in control technology, these control algorithms have advanced to the state where these mathematical functions are now able to closely approximate human reasoning. The authors review where fuzzy logic started and then examine where fuzzy logic is today
