Delay-dependent robust H∞ control for T-S fuzzy descriptor networked control system with multiple time delays

The problem of delay-dependent H_∞ control for T-S fuzzy descriptor networked control systems with multiple state time-delays has been investigated. In terms of linear matrix inequality approach, an improved delay-dependent stability criterion, which ensures the system is regular, impulse free and satisfied with a prescribed H_∞ performance condition, is given without using model transformation and bounding technique for cross terms. With the proposed criteria, we are able to obtain maximum allowable delay bound (MADB) of NCSs. Numerical example is provided to demonstrate the efficiency of the proposed methods.
