Modelica-based modeling and simulation of satellite On-orbit deployment and attitude control

In order to reflect the dynamic characteristics of satellite on-orbit deployment more precisely, a Modelica-based modeling and simulation of satellite on-orbit deployment and attitude control was achieved. Form Modelica standard library, world component was extended, this simulation system integrates Space perturbation factors and Celestial time scales. Based on Modelica Object-oriented character, synchronous deployment model of satellite solar panel was developed, satellite on-orbit deployment by integrating Space perturbation functions and keplerian orbit parameters were achieved. Based on Modelica united modeling character, between direct and inverse model, the inverse dynamic attitude control system was constructed. The simulation of satellite On-orbit deployment and earth-oriented attitude control, verifying whether the satellite on-orbit deployment demands the overall design of satellite, supporting rapid prototyping during all phases (project proposal, subsystem, system, etc.).
