ANZLIC2019: 'In contrast to traditional digital models, digital twins can connect with the physical ‘twin’ they model, changing alongside the physical system via real-time sensors and actuators.'And borrowing also some definition help:
Wikipedia: 'A sensor is a transducer that receives and responds to a signal or stimulus from a physical system. It produces a signal, which represents information about the system'
Webel Twin Pattern: A DigitalTwin manages a control loop including a PhysicalEntity and a DigitalEntity (a.k.a. @Entity) that «replicates» it. It typically includes at least one Sensor and at least one Actuator.Note that bit about variants again! The
ControlSystemcan play with any number of variants separately and use them to help drive the
PhysicalEntityinto a desired state (as then measured later by sensors or other reliable data sources):
Webel Twin Pattern: The primary aim of the digitalEntity:@Entity of a DigitalTwin is to replicate its physical:PhysicalEntity as closely as possible (not to explore variants).
Webel Twin Pattern: A DigitalTwin may use one or more variantEntity:@Entity[0..*] to explore the impact of changes (optimisation studies, trade off studies) and then use them to drive the PhysicalEntity into a desired state (via its ControlSystem).Please note again also that the terms 'sensor' and 'actuator' are used in the most general way:
