EPS Control for a CubeSat

Abstract

This research work focuses on modeling and simulating energy cycling tests to characterize the Li-S battery of the academic CubeSat “PdQSat” payload and establishing an interface between the battery and the satellite’s EPS for emergency energy supply. Utilizing Supervisory Control Theory (SCT) of Discrete Event Systems (DES), the study aims to guarantee a well coordinated transition between the satellite’s operational modes during the mission. The integration of models developed in previous works, along with the synthesis of SCT plants and supervisors, form the core of the methodology. The simulation of these components allows for the analysis of their closed-loop behavior in various situations, such as in extreme conditions. The study also delves into fundamental theories such as Supervisory Control Theory, Orbital Mechanics, Battery Management Systems, and Reliability to provide a comprehensive understanding of the subject matter. Through collaborative efforts with advisors, colleagues, and contributors, this work contributes to the advancement of control systems in aerospace engineering.
