Fuzzy Logic Control System for Reconfiguration Procedure Appliedto the NASA Benchmark Tetrahedron Constellation

摘要

The NASA Benchmark Tetrahedron Constellation is a complexrnconfiguration that involves three different specific sizes. Thernreconfiguration procedure to move from one specific size to thernnext one is complicated and may involve complex numericalrnprocedures. The objective of this paper is to present a fuzzy logicrncontrol system in which the reconfiguration procedure of therntetrahedron constellation can be done without the necessity of arncomplex mathematical formulation. The Lagrange Planetaryrnequations are used to achieve this reconfiguration procedure. Thesernequations represent a highly non-linear set, but, by extractingrncertain data, the fuzzy control can be used as a non-linearrncontroller. Hence, the fuzzy control system will give a differentrnperspective in the use of control systems for space applications inrnreconfiguration procedures.
