DOI: 10.1109/tsmc.2022.3145508
Abstract: A novel adaptive multivariable control algorithm is proposed for reusable launch vehicle (RLV) subject to bounded but unknown disturbances. In the proposed algorithm, a time-varying nonoverestimated adaptive gain is designed based on the prescribed performance… read more here.
