Microsatellite Solar Array Regulator Digital Twin Development and Validation

In this work it is presented the development and validation of a Hardware-in-the-Loop (HIL) digital twin for a microsatellite solar array regulator. The Typhoon HIL platform and the SAR, previously developed by the authors, have been used to develop and validate the digital model. Moreover, in order to get the most out of the digital model, three different types of implementations have been carried out, which are the following: digital twin HIL, where all the solar array regulator functions have been implemented in the HIL platform; power HIL, where all the power electronics subsystems have been implemented in the HIL platform but the control part is implemented in hardware; and controller HIL, where the control subsystem is implemented in the HIL platform and interacts with hardware power electronics parts.
