Constant Tension Control System Study Of Rubber Belt Manufacture Machine

The main objective of this paper is to control the tension of enforced cord in rubber belt so that the tension is constant in manufacture process. In order to overcoming the shortcomings existing in production machine of rubber belt, we analyzed all kinds of factors that affect the tension, and then brought forward the double control method. That is: First we control rotate speed stability of principal-axis, second we control tension of cord in belt. Moreover control principles and methods have been analyzed and hardware has been designed in each control part. Further more, after analyzing the mathematical model carefully, we designed a mixed cord tension controller based on the combination self-tuning fuzzy control and double state control and also made a deeper research on the high precise invariable tension fuzzy control method in this part. At last, we discussed distributed Control System in this thesis and raised a new method of time-shared rule that a monitor with neural network technology regulated each of the field fuzzy controllers based on numerical single chip microcomputer. This method is kind of half-onlineregulation.
