摘要：

A Terminal sliding mode control (TSMC) based on fast fuzzy disturbance observer (FFDO) is proposed for the UASV re-entry with violent changes of aero-dynamics parameters. To achieve high precision, an FFDO is designed which improves the approximation ability of the observer on-line. The finite time convergence characteristic of TSMC improves the tracking speed of the flight control system. Combining TSMC with FFDO, the flight quality is guaranteed. Finally, the simulations demonstrate the superiority of the FFDO and the effectiveness of the closed-loop control scheme.
