Nanosatellite nonlinear attitude control testing on an air bearing system

open access: yes, 2012
While nonlinear attitude control has been explored widely in theory, nanosatellite air-bearing-based spacecraft simulators have not been used to test nonlinear discrete time control techniques.

Fault Tolerant Control for Nanosatellite Using Adaptive Sliding Mode Control

open access: yes, 2012
본 논문에서는 나노위성의 고장허용제어 기법을 제안하였다. 나노위성의 모델의 부피는 10cm⋅10cm⋅20cm 이며, 반작용 휠을 구동기로 쓰는 모델이다. 반작용 휠의 고장을 시스템의 불확실성으로 반영하였다. 그렇기 때문에 갑작스럽게 일어난 반작용휠의 고장에 위성이 강건하게 반응한 제어 시스템을 갖도록 하였다.
