Reaction wheel design for CubeSats

This paper presents a reaction wheel design for Cube-Sats where it takes the limitation of size and mass into consideration. It presents an overview of which altitudes it is feasible to use magnetic torquers for momentum dumping as well as presenting equations for customizing reaction wheels for a Cube-Sat mission. The reaction wheels are then simulated for different Cube-Sat sizes and proved capable of performing attitude maneuvers. During these simulations a non-linear passivity-based sliding surface controller is used which through Lyapunov stability theory has been shown to be uniformly asymptotically stable.
