A survey of networked control systems with delay and packet dropout

Networked control systems (NCSs) are feedback control systems with control loops closed via digital communication channels. This paper reviews the recent results on network-induced delay and packet dropout. The approaches dealing with continuous-time NCSs with delay are reviewed, and the jump system approach is presented to model the variation of delay. The non-uniform distribution characteristic of network-induced delay is taken into full consideration, and the linear estimation-based packet dropout compensation method is reviewed.
