Observer based networked control systems with network-induced time delay

The time-delay characterizations of the network transmission and device processing are very important to analysis and design of networked control system. Modeling of networked control systems is described and analysis of networked control system is carried out. Then state observer of the networked control system with time delay is derived in this paper and modeling of networked control system based on state observer is built. Finally simulations of networked control system based on state observer with time delay and without time delay are carried out respectively. A good performance of the NCS with time delay based on the state observer is obtained.
