Dynamic Modeling and Control of Pressure Dyeing Machine's Running Roller System

摘要

Key factor determining production quality is the deformation control between running rollers of pressure dyeing machine during the operation. Currently the industrial communities try to alleviate the defects by taking experiments. This study aims to approve theoretical practicality of providing controller and its parameters suitable to abolish vibration displacement in operating pressure dyeing machine in order to improve pressure dyeing quality and lengthen machine's life. Firstly, the dynamic equation of the pressure dyeing machine's running roller is derived and its corresponding open-loop transfer function is obtained from modal summation method. Then, the root locus method is used to design a controller which is realizable in the industrial communities. Simulation indicates that the designed controller not only can eliminate vibration response generated during pressure dyeing process and reducing greatly the previous process defects by making the two running rollers smoothly contact with each other. The solution is a high efficient way to ameliorate pressure dyeing process with low cost and easy access.
