Simulation of complex dynamic systems
To promote virtual testing and optimization of related systems, after modeling and verification, it is necessary to implement system integration. Currently, there are so many challenges in system simulation field, such as low efficiency of integrated model, rebuilding heterogeneous models with different simulation tools, lack of standarized virtual testing process and so on. Based on the engineering experience coming from related European Commission industry projects in last years, SIMTEK has strong ability to model and simulate dynamic models of complex systems using Modelica language and FMI standard in a very standardized and efficient way. By modeling systems in proper detail level, SIMTEK replicates the essential process occurring in real systems, adapts to different needs of product development cycles, and deeply explores the actual physical characteristics and control logic of the system. SIMTEK provides professional and comprehensive system simulation services, such as
- System model integration
- Modeling requirements and acceptance criteria
- Assist customers to integrate & accept models
- Virtual testing and verification based on integrated model
- SIL & MIL & HIL
- Design and development of virtual model automatic test platform
Model-based Optimization
System optimization is typical application by using advanced modeling and simulation technology. Optimization tasks include the optimization of the core parameters in the control algorithm, system model architecture and the parameters of the core components. By means of high precise models and optimization tools, the iterative optimization for software can be realized. It can significantly increase the efficiency of product development and design. In the past projects with leading industrial companies such as Airbus, BMW, Daimler and so on, model based optimization was always a essential topic. As shown in the figure, it is an optimization-based framework for fast steady-state calculation, built by SimTek team members within Airbus power quality analysis project.
