Delay-dependent Robust H∞ Control for T-S Fuzzy Descriptor Networked Control System with Multiple State Delays

The problem of delay-dependent robust H∞ control for T-S fuzzy descriptor networked control systems with multiple state time-delays is investigated. First, in terms of linear matrix inequality (LMI) approach, an improved delay-dependent criterion is established to ensure that the descriptor system is regular, impulse free and stable with H∞ performance. Without using model transformation and bounding technique for cross terms, the criterion is less conservative. With the proposed criteria, we are able to obtain maximum allowable delay bound (MADB) of NCS. Numerical example shows that the proposed criteria are effective and less conservative.
