Stability of Networked Control Systems: A New Time Delay Systems Approach

A large number of research works on Networked Control Systems (NCSs) are from the time delay system perspective, however, it is noticed that the description of the network-induced delay is too general to represent the practical reality. By recognizing this fact, a novel time delay system model for NCSs is thus obtained by depicting the network-induced delay more specifically, inspired by the packet-based control approach. Based on this model, stability (robust stability) and stabilization results are obtained using delay-dependent analysis approach, which are less conservative compared with conventional models due to the specific description of the network-induced delay in the new model. A numerical example illustrates the effectiveness of the proposed approach.
