INTRODUCTIONNetworked control systems (NCSs) are described as the spatially distributed systems in which the sensors, actuators, and controllers are connected via a shared communication network. In comparison with traditional systems, the NCSs possess many advantages such as great flexibility, convenient maintenance, low cost of installation, and so on. Yet, along with these advantages, some challenging issues (bandwidth allocation, communication delay, packet dropouts, packet disorders, and channel fading) emerged and gave rise to much attention. Then most recently, the research on the NCSs has become a heated topic and many elegant results have been proposed. 1-29 For instance, in Reference 1, an optimal linear filter for the NCSs was designed with involving time-correlated fading channels.As for distributed NCSs, in Reference 2, both communication constraints (packet dropouts and quantization) and switching topology were addressed. Meanwhile, since communication delay inevitably exists and leads to poor performance, then References 3-7 deeply studied its negative effects when designing the controllers. In Reference 3,
