Overview

The use of Nano Satellite in space missions has generated a lot of interest due to their compact size and relatively low development, launch and operating costs compared to larger satellites. This allows for launches that are more frequent and the ability to replace or upgrade satellites more frequently. The stability of Nano satellite is crucial for its successful operation in space, and designers and engineers must take various measures to ensure that the satellite is able to maintain its orientation and position in space throughout its mission Indeed. The proposed control approach is based on backstepping control theory and uses adaptive control to handle actuator uncertainties and faults. The control system is developed for 3-axis stabilization and its performance is illustrated in numerical simulations. The results show that the proposed control approach can successfully maintain the stability of the Nano satellite under actuator failure compared with classical backstepping control.
