Diameter Real-Time Computing of Uncoiler/Coiler Machines Based on the S7-300

Abstract:

Application of coil diameter calculation is very important in the industrial field. The demanding for the precision of control is increasingly strict. There are three methods to achieve a higher precision. They are the Count-method, Linear /Angular Velocity and Distance Calculation respectively. In the process of coiling and uncoiling, advantages and disadvantages are existed. There are different requests for realization of the functions as well. In the Siemens PLC S7-300 control system, these three methods can be used to achieve a higher precision of coil diameter calculation and control. Different improvements and adjustments, according to methods, are given in the process of the test. Some algorithm has been optimized. Finally, by using the three algorithms, the dynamic change of roll diameter can be calculated and meet the need in the course of steel strip.
