| 英文摘要 |
| The fuzzy fault-tolerant control problem is studied for global stabilization of a class of uncertain nonlinear
interconnected large-scale systems with unknown time varying time delays. The unknown delayed input signals of the
fuzzy approximator are substituted by the bounded references signals, and as a result, the control design and application
are not dependent on the delay assumptions any more, so that the convenience of the controller design and application is
greatly improved. The fault-tolerant backstepping control and the adaptive control technique are combined to deal with the
errors of the replacement and the approximation. The proposed control scheme can compensate for all of the four types of
actor faults efficiently, and global stability of the closed-loop system is guaranteed. Simulation results are provided to show
the effectiveness of the control approach. |
