Evaluation of Power Control System for Micro and Nano Satellites by Hardware-in-the-Loop Simulator

The evaluation method using Hardware in the Loop (HIL) simulator of power control system for micro and nano satellites is suggested. The results for two satellite projects, which are RISING-2 and RAIKO, are described. The generation power by solar panels and the consuming power by electrical units are supplied or consumed by external instruments. The power-related status data of real satellite are measured via the downlink. As a dummy satellite, satellite simulation software is simultaneously executed, and the status data are compared to ones of real satellite for updating the math models. Through this method, the power environment on orbit can be simulated in a long-term span, and the healthiness of electrical system can be sufficiently evaluated in a ground test
