ISG-virtuos is a powerful simulation platform of the ISG Industrielle Steuerungstechnik GmbH. It enables the representation of components, machines or entire plants as digital twins for an application across all product lifecycle phases. ISG-virtuos is a scalable, modular system that allows different simulation types, such as kinematics, dynamics or physics simulation, as well as different expansion levels of the simulation environment: Model-in-the-Loop (MiL), Software-in-the-Loop (SiL) and Hardware-in-the-Loop (HiL). Other characterizing features are real-time capability and fieldbus communication. With its parameterizable simulation model for ISG-virtuos, Bosch Rexroth offers powerful digital twins for its extensive ctrlX DRIVE portfolio and the associated motors.
Machine simulation in the context of a simulation environment
The application of simulation models within a simulation environment like ISG-virtuos is used, for example, to simulate an entire machine or plant. In addition to the electric drives, the corresponding mechanics, kinematics and other peripheral components are also simulated. The input and output data of the different simulation models are connected in the simulation tool. For example, a mechanical component driven by an electric drive can be modeled by means of a drive, mechanics and kinematics model in such a way that a light barrier, which is also implemented in the simulation, is triggered by the kinematics model and the simulated light barrier signal is fed back to the controller in order to control further machine processes.
Use cases
Bosch Rexroth offers customers comprehensive, parameterizable simulation models for ISG-virtuos for its drive systems and motors of the ctrlX DRIVE product line for the following use cases:
- Detailed sizing, configuration and parameterization
- Mechatronic machine & system optimization
Machine & system performance estimation - Virtual rapid prototyping via HiL, SiL
- Virtual commissioning (VIBN) and acceptance tests
- Training
The model covers the complete behavior of the ctrlX DRIVE, both the control loop behavior and the state machine behavior. That is why it is a real Digital Twin.
Benefits
- Reduced commissioning and programming times and costs by using digital twins for virtual commissioning and other use cases like performance optimization or trainings.
- Reproduction of the communication, sequence behavior and the control loop as a part of simulation environments for complete machines and plants.
- Flexible usage for different kinds of simulation and simulation architectures (Real-time and Non-real-time, HiL, SiL).
- Realistic working mode through the use of ctrlX DRIVE Engineering in combination with the virtual ctrlX DRIVE.
