| 英文摘要 |
| The finite time attitude tracking control problem is investigated based on disturbance observer for the reentry
hypersonic vehicles with bounded external disturbances and model uncertainties. Firstly, the attitude model is divided into
a two-loop structure based on the multiple time scale technique, and then terminal sliding mode controllers are designed for
each loop. Secondly, disturbance observer is designed to estimate external disturbances and uncertainties, and the chattering
caused by the big controller parameters of the sliding mode control can be eliminated. Stability is presented on the basis
of Lyapunov analysis. Finally, simulation is carried out to demonstrate the effectiveness of the proposed controller for the
6-DOF reentry model. |
