Digital Twins in Mechatronics: From Model-based Control to Predictive Maintenance

Fault diagnosis systems are essential in precision mechatronics to facilitate maintenance and to minimize downtime. The aim of this paper is to describe the current trend in control for precision mechatronics and the related future challenges for digital twin-assisted predictive maintenance as well as recently developed approaches. The future generation of fault diagnosis systems is envisaged to rely on identified physics-based models, enriched by the available real-time data from a large number of sensors and actuators.
