Abstract

Abstract:

It is necessary to take into account the speed of the system when researching the co-simulation coupling system. The linear recessive stabilization method can accelerate the simulation operation time under the premise of ensuring the stability of the system. The simulation efficiency and simulation accuracy can also be taken into account when researching the co-simulation coupling system. The engineering example under the FMI standard based on joint simulation also proves that this method makes the system have good stability and accuracy, and compared with the reference simulation, the system has higher simulation efficiency. For large-scale system modeling solutions in multiple fields, a simulation method based on the FMI universal interface standard is proposed. The modeling simulation verification of the FMI standard combined with the Dymola platform can be achieved using the method.
