Recently, networked systems have gradually become an active area of research due to their advantages in many aspects such as low cost, reduced weight and power requirements, and simple installation and maintenance, as well as high reliability. It is well known that the devices in networks are mutually connected via communication cables which are of limited capacity. Therefore, some new challenging issues have inevitably emerged, for example, network-induced time delay, data missing (also called packet dropout or missing measurement), and quantization effect, all of which should be taken into account in order to achieve the required performance of the NCSs. These issues are usually referred to as incomplete information.

Networked systems consist of large groups of cooperating dynamic systems which have made significant impact on a broad range of applications, including complex networks, mobile sensor networks, and genetic regulatory networks. To meet the application requirements, new analysis/synthesis paradigms are needed which must necessarily depart from classical centralized analysis/control strategies. In many of the applications envisaged, however, the highly distributed nature of the sensing and actuation modules of the networked systems have made it difficult to tackle the problems under the framework of traditional dynamical theory.

Networked systems with incomplete information (NSII) have already become an ideal research area for control engineer, mathematicians, and computer scientists to manage, analyze, interpret, and synthesize functional information from real-world networked systems. This special issue aims to bring together the latest approaches to understanding, estimating, and controlling NSII in a quantitative way. Potential topics include, but are not limited to:

• Synchronization and control with incomplete information
• Topology structure and dynamics with incomplete information
• Stability analysis with incomplete information
• Robustness and fragility with incomplete information
• Applications in real-world networked systems
