With the development and integration of theories of information, communication and control, large-scale and spatially distributed control systems over wireless digital channels are now widely applied in intelligent transportation, industrial automation and advanced manufacturing, for instance. The use of wireless networks in control systems allows for modular and flexible system design, e.g., distributed processing and interoperability, simple and fast implementation, e.g., reduced wiring and powerful configuration tools, and reduced installation and maintenance costs. However, the analysis and design of such systems pose new challenges due to packet loss, data quantization, channel fading, communication delay, asynchronous sampling, for instance. In the past decades, although some fundamental aspects have been studied, there are several open issues that still need to be addressed such as the performance analysis of networked systems, the modeling and congestion control of wireless networks, co-design of wireless networked control systems, distributed estimation and control.
