| 英文摘要 |
| Researches and analyses are conducted for the finite-time tracking problems of hypersonic vehicle longitudinal
model with external disturbances and uncertainty of the model parameters. When external disturbance upper bound
is known, the finite time fast integral sliding mode controller is designed based on the fast integral sliding mode theory.
When external disturbance upper bound is unknown, the auxiliary system is introduced to design the anti-saturation practical
finite time adaptive fast integral sliding mode controller which is combined with a kind of adaptive algorithm with low
pass filter performance and can handle input saturation. Strict proofs are given using the Lyapunov theory for the above
two controllers, which shows that the whole state of the closed-loop system is respectively finite-time stable and practical
finite-time stable. Also the proofs shows that other state variables of the system can tend to steady values in a short transient
process. For different types of reference signal, numerical simulations are presented which further demonstrate that the two
designed controllers have strong effectiveness and robustness. |
