| 英文摘要 |
| For a class of networked control systems (NCSs) with time-delay and integral quadratic constraints
(IQC）performance, we investigate the H-infinity fault-tolerant control under the unequal interval sampling. First of all,
the relationship between the delay and the unequal interval sampling in the NCSs is analyzed and processed. On this basis,
the switching model of NCSs with uncertain time-delay under unequal interval sampling is built. By constructing Lyapunov
function, using H-infinity control method, and designing controller with IQC performance, the delay-dependent stability
criterion based on LMI description systems is obtained. Then, the sensor fault model and the mathematical model of NCSs
under the sensor fault are built. By applying the conclusion to the NCSs with sensor fault，we obtain the stability criterion
of the systems under H-infinity fault tolerant control. By comparing the performances of a given example with that obtained
from other existing methods, we confirm the feasibility of the presented method. |
