Type: article
Abstract: The utilization of nanosatellites in space missions has sparked significant interest owing to their compact size and relatively economical development, launch, and operational expenses in comparison to larger satellites. This cost-effectiveness facilitates more frequent launches and the capability to replace or upgrade satellites with greater frequency. The stability of nanosatellites is paramount for their successful operation in space, necessitating designers and engineers to implement various measures to ensure the satellite maintains its orientation and position throughout its mission. In this paper, an adaptive control methodology relies on backstepping control theory is suggested to address the multiplicative faults in the actuators. Specifically, the control system's efficacy is demonstrated through numerical simulations for 3-axis stabilization. The outcomes reveal that the proposed control approach adeptly sustains the stability of the nanosatellites in the event of actuator failure, outperforming classical backstepping control.
