The high integration of physical processes and cyber infrastructure greatly promotes the speedy growth of cyber-physical systems (CPSs), which has been turning into a critical essence of the so-called fourth industrial revolution. Benefiting from close coordination with computational resources and ubiquitous communication capacities, the CPS reveals the merits of greater autonomy, efficiency, functionality, reliability and adaptability. In the past few years, the theoretical investigations and technology applications of industrial CPSs referred to intelligent transportation networks, power/gas/water generation, distribution arrangements, multiple industrial robot, and thus onward. It is worth pointing out that, for real-world engineering, the limited channel bandwidth and the security vulnerability of communications may result in various network-induced phenomena and the unreliability of exchanging data, such as data missing, communication delays, denial of service attacks, deception attacks and so forth. Furthermore, communication scheduling among different physical components could lead to the sparsity of received data while reducing the occurrence of communication congestion. There is no question that they can be regarded as sources of the negative effects on the precision of control and filtering. As such, the performance analysis and synthesis of industrial PSCs have generated increasing interest in research and many crucial issues deserve further consideration.
