Delay-Dependent Robust Stability for T-S Fuzzy Descriptor Networked Control System with Multiple Time Delays

Abstract

This paper deals with the problem of delay-dependent stability for T-S fuzzy descriptor networked control systems with multiple state time-delays. Without using model transformation and bounding technique for cross terms, an improved delay-dependent stability criterion is established in terms of strict linear matrix inequalities (LMIs), which ensure the system is regular, impulse free and asymptotically stable. With the proposed criteria, we are able to obtain maximum allowable delay bound (MADB) of NCSs. Numerical example shows that the proposed criteria are effective and less conservative.
