Robust H-inf control of distributed networked control systems with variable structure and partly networked information

In this paper, the distributed networked control systems (DNCSs) are considered. The states of each sub-system are divided into the exact local parts and the inexact remote ones, which are transported through a communication network from other sub-systems. Such information will be quantized and may be lost during the transporting. Moreover, variable structure of the DNCSs is also considered and a Markov process is used to model such situation. Based on Lyapunov-Krasovskii (L-K) approach, a mode-based state feedback controller is proposed to stable such DNCSs and to meet the robust H-inf performance in terms of bilinear matrix inequalities (BMIs). Further, a cone complementary algorithm is given. Finally, the proposed method is validated through a simulation example.
