Co-simulation of Saber and Simulink-based PPT satellite power controller

The purpose of this paper is using Saber-Simulink co-simulation to verify effectiveness of the peak power tracking (PPT) satellite power controller and rationality of this co-simulation method. First of all, a model of the satellite power supply controller is created in MATLAB/Simulink, including a PPT controller module, a mode conversion module as well as a constant current-constant voltage (CC-CV) charge controller module. Then combining the advantages of both Simulink and Saber, the definition method of their interfaces is introduced particularly, and then co-simulation of satellite power system was completed. The results show that the satellite power controller works normally, so the Saber-Simulink co-simulation is a reliable method of system simulation, and it is suitable for the simulation of satellite power controller.
