Development of a digital twin for an elevator system

Abstract

The increasing digitalization of production processes and current technological developments make it possible to use sophisticated digital product models or virtual images of industrial and technical processes, so called digital twins. In this paper a digital twin is created using different development environments and systems, such as Simulink®, B&R® control, CAD design environment and OPC-UA communication. The creation process used is verified and simulations are performed with the created digital twin to test and validate its behavior and efficiency compared with the physical model. Then the two systems, which are the digital twin and the elevator model, are linked together so that the communication between the two can be verified. The ability to communicate with the real world is one of the main characteristics of an optimal digital twin.
