Abstract


Shaftless presses with high driving accuracy , simplified structure , a wide range of gear ratios , adjust and easy , it has gradually replaced the traditional mechanical long axis of the printing press and the development trend of the future of the printing industry . After years of research, many scholars have proposed for shaftless drive system the synchronization control strategy , so far, for the shaftless printing machine synchronization control system is still hot and difficult . Face due to various factors is not synchronous , seeking multi-axis high-performance synchronous movement is still a pressing problem . In this paper, the problems that exist in the shaftless presses synchronization control exploratory research . This article first shaftless printing press for the study , after analysis of the of shaftless technology advantage and learn the basics shaftless presses synchronization control , common in several multi-motor synchronous control mode for axis the drive presses synchronization control system design electronic virtual the total axis synchronization control strategy , simulation results show that the electronic virtual the total axis control strategy to meet the multi-axis system speed synchronization and position synchronization requirements (greater than two-axis ) , suitable to be applied shaftless the synchronous control system of the printing press . Secondly, research the sliding mode control algorithm based on Sliding Mode Variable Structure Controller axis system designed to improve the tracking performance and robustness of the system ; and for the actual operation of the process , the drive motor load torque changes and other factors impact the synchronization accuracy , the design of adaptive sliding mode variable structure controller based on integral switching function . Finally , the entire shaftless presses synchronous control system design and system simulation in MATLAB environment , the simulation results show that the proposed control strategy can not only achieve shaftless presses synchronization control , and synchronization impact of system parameter changes , the system location can be effectively suppressed , to achieve the purpose of research .
