Fault injection in Digital Twin as a means to test the response to process faults at virtual commissioning

Digital Twin (DT) is one of the pillars of modern information technologies that plays an important role on industry digitalization. Its use varies very much with the domain but one of them, encouraged by integrated frameworks that cover the whole life cycle of manufacturing applications, is during Virtual Commissioning phase. This paper presents both a design and implementation methodology to easily test the control system reaction to process faults. In particular, the way to prepare the DT to support fault injection is analyzed. The proposal is tested through a simple but representative case study.
