Abstract: As a digital image of the real space station，the digital space station integrates multiple professional models such as energy，information，environment and thermal control，dynamics and control，and establishes a multi disciplinary simulation system at the module level and the whole station level to provide technical support for the long term flight control mission of the space station.Based on Modelica and FMI，the integration of digital space station dynamics and control simulation model is completed and successfully applied in space station flight control.

Key words: digital space station, multidisciplinary simulation model, dynamic and control, flight control
