Abstract
The problem of integrity against sensor failures for the nonlinear networked control systems in which the plant can be described by T-S fuzzy models is studied based on state observer. Assuming that the time-delay is less than one sampling period, the system is modeled as a discrete time T-S fuzzy model with parametrical uncertainties. Based on the model, the fuzzy state observe is designed and according to possible sensor failures, an augmented mathematic model for the systems based on the fuzzy state observer is developed. Then the sufficient stability condition of integrity against sensor failures is given and the designs for fuzzy fault-tolerant controller and fuzzy observer are presented by using the theory of fuzzy control and the approach of Matrix Inequalities.
