New delay-independent stability analysis for discrete fuzzy time-delay control systems

This paper is concerned with the stability issue of the discrete Takagi-Sugeno (T-S) fuzzy control systems with time-delay. The information of premise membership functions of the fuzzy time-delay model and fuzzy controllers are all considered in stability analysis. A new delay-independent stability criterion in terms of linear matrix inequalities (LMIs) is proposed. Finally a simulation example is presented to illustrate the less conservativeness of the proposed results.
