Abstract:

The problems of stability and state feedback control for a class of discrete-time T-S fuzzy descriptor systems are investigated in this paper. Based on fuzzy Lyapunov function, a set of slack variables is introduced to remove the basic semi-definite matrix inequality condition to check the regularity, causality and stability of discrete-time T-S fuzzy descriptor systems; a new sufficient condition for the discrete-time T-S fuzzy descriptor systems to be admissible is proposed in terms of strict linear matrix inequalities (LMIs). And a sufficient condition is proposed for the existence of state feedback controller in terms of a set of coupled strict LMIs. Finally, an illustrative example is presented to demonstrate the effectiveness of the proposed approach.

Key words:  T-S fuzzy descriptor systems  parameter uncertainties  stability  state feedback control  linear matrix inequality (LMI)
