Application and research on digital twin in electronic cam servo motion control system

Abstract

With the development and extensive applications of big data and artificial intelligence (AI), the manufacturing industry is gradually becoming increasingly intelligent. In the industrial sector, digital twin can greatly promote the innovation of products in the processes of design, production, operation, and maintenance. The traditional cam mechanism in mechanical reciprocating motion is constrained by the profile curve and lacks flexibility, which will be replaced by a new, flexible and controllable electronic cam. This paper designs a digital cam servo motion system based on digital twin. Using the multi-dimensional simulation software and taking advantage of virtual-real interaction ability of digital twin technology, the trajectory planning, state monitoring, and precise control of the electronic cam motion can be realized. The results show that the electronic cam servo motion control driven by digital twins has good observability, robustness, and adaptability. The scheme is feasible and practical, and provides reference for the design, manufacture, and application of electronic cam using digital twin technology.
