A survey of packet disordering existing in networked control systems

Packet disordering of networked control systems has be attracted great attention in recent decade. This paper provides a survey of packet disordering problem in control and synthesis of networked control systems. The contents in this survey involve reasons caused packet disordering, metrics of packet disordering, modeling packet disordering for networked control systems, analysis of relationship among packet disordering, network-induced delay and packet loss, impacts of packet disordering on control performance of networked control systems are investigated as well. Furthermore, future research directions and open problems are also proposed.
