英文摘要 |
This paper proposes a global sliding mode flight control method with switching gains adaptation for low
altitude heavyweight airdrop operations, in the presence of uncertainties whose bounds are not known. This method uses
the feedback linearization technique to decouple the nonlinear heavyweight airdrop model, thus solving the strong nonlinear
problem of the system. On this basis, a global sliding mode controller with switching gains adaptation is presented. It
guarantees the global robustness of the system and overcomes the influence of the initial errors in the reaching phase of
the sliding mode to the switching gains adaptation process. A modified gains adaptation method is proposed, which solves
the overestimation problem of the switching gains in the sliding phase of the sliding mode. The stability and robustness
properties are proved by using the Lyapunov theory. The control performance as well as the advantage of the proposed
method is evaluated in a number of simulation scenarios. |
