|Robust Control of Spacecraft: Application to an Actuated Simulator
International Journal of Control, Automation, and Systems, vol. 16, no. 2, pp.896-903, 2018
Abstract : "In this article, a hardware-in-the-loop implementation of two robust controllers based on high-order sliding
mode and m-synthesis method are performed and compared in terms of performance and functionality. The
spacecraft simulator consists of a free-floating platform hinged on a spherical air-bearing support. The proposed
scheme makes full use of adaptive super twisting algorithm to alleviate the chattering effects without increasing
the control effort; both controllers are adapted to deal with the saturation of reaction wheels with respect to momentum
and its rate of change. The ab-initio simulations compared well with the simulator responses, implying
that involved instruments including actuators and sensors have been properly emulated. This also proved that the
external disturbances were modeled in a reliable manner. The robustness and effectiveness of the proposed scheme
have been validated experimentally under extreme circumstances and uncertainties."
