What is A Novel Satellite Layout Optimization Design Method Based on Phi-function about?

The purpose of this paper is to present a novel satellite layout optimization design (SLOD) approach based on the phi-function, which provides a simple, effective and simultaneously accurate way to handle the geometry constraints (including non-overlapping constraint and distance constraint) with an explicit mathematical expression. Firstly, an extended basic SLOD model concerning the system mass characteristics is formulated with the introduction of a generic minimum/maximum distance constraint between components. In the previous literature, most of the investigated SLOD applications only involve the planar circular and rectangular components with fixed orientation due to the lack of an effective and accurate overlap calculation method, let alone control the distance between them. Therefore, the idea of using phi-functions to prevent overlap and control distance between components is put forward to alleviate this difficulty. Furthermore, to effectively prevent the container protrusion from the components, the phi-function method is extended by our proposed finite-component-boundary (FCB) method. Despite its positive effects, the limitation of the phi-function is clearly discussed
