| With the expansion of the market share of gravure products,electronic shaft gravure printing machine has been widely used,and people have higher and higher requirements for printing speed,printing precision and anti-interference performance.After many scholars have studied,the performance of the steady-state phase has been further improved,and the performance of dynamic phases such as acceleration and disturbance has yet to be improved.The performance of dynamic phase is also an important indicator for measuring the performance of electronic shaft gravure printing machine.The modeling and synchronous control of dynamic phase of the electronic shaft gravure printing machine are very important.In order to improve the synchronization performance and anti-interference performance of the dynamic phase,this paper takes the dynamic phase of electronic shaft gravure printing machine as the research object,and analyzes the tension instability and synchronization in the dynamic process such as acceleration and disturbance according to the printing process and working principle.The error model of the dynamic phase is established.The virtual spindle synchronous control strategy and the variable universe fuzzy PID control algorithm are designed to control the system.The virtual spindle synchronous control strategy adjusts the input of each shaft according to the actual running state of each physical shaft feedback.The variable universe fuzzy PID controller changes the input and output universe according to different operating phases of the system,and the system is adjusted in real time.Finally,a physical experiment platform is built to transplant the control strategy and control algorithm to verify its performance.The simulation and physics experiments show that the model established in this paper can describe the characteristics of dynamic phase well.The virtual spindle synchronization control strategy and the variable universe fuzzy PID control algorithm can reduce the synchronization error and improve the printing precision and anti-interference performance of the dynamic process. |
