Power System Topology Proposal of a High-Altitude Pseudo-Satellite: Sizing Method, Power Budget Modeling and Efficient Power Control

Abstract

In aerospace research, the High-Altitude Stratospheric Platform System (HAPS), is becoming an effective alternative solution to perform Earth observation missions, where several problems faced by aircraft systems can be solved. The most important advantages of HAPSs are their manufacturing and launch cost reduction compared to the satellites, with enough durability to provide services as satellites do. For a successful HAPS mission, it is imperative to assess the feasibility of their deployment in a given location, where, the energy generation and consumption are the main constraints. Therefore, the conception of an Electrical Power System (EPS) has been considered as a fundamental issue in HAPS development. In this paper, a proposed EPS topology, for HAPS dedicated to Earth observation missions, is presented with a proposed sizing method, power budget modeling, and a novel efficient power control based on fuzzy logic approach.
