Reliable fuzzy stabilization against sensor faults

Reliable control problems for T-S fuzzy systems with sensor faults are studied in this paper. For a class of fuzzy systems, the premise variables of which are dependent on the system states, a type of new conditions for designing fuzzy reliable controllers are proposed by applying the properties of product inference engines. In contrast to the existing approach, the new conditions are with less conservatism for T-S fuzzy system with partly unmeasurable premise variables. An example is given to show the advantage of the proposed approach.
