| 英文摘要 |
| This paper addresses the problem of integral-type sliding mode robust fault tolerant control for spacecraft , in
the presence of actuator failures and external disturbances simultaneously, achieving the finite-time attitude stabilization.
As a stepping stone, a simple saturated nominal controller is firstly designed using homogeneous system theory, to ensure
finite-time attitude stabilization of spacecraft without failures and disturbances. Then, utilizing integral-type sliding mode
and adaptive techniques, a novel finite-time robust fault tolerant control strategy is developed to compensate for actuators
failures and external disturbances. And also, the chattering problem has been restrained via a gain adjusting law. Finally,
numerical simulation results are presented to illustrate and highlight the fine performance benefits obtained using the
proposed scheme, especially for the faster and higher-precise attitude stabilization. |
