Stability of networked control systems with communication constraints

Considering the constraints of network bandwidth,multiple-packet transmission was adopted here in the networked control system(NCS).To avoid the wrong order of these network packets,only one packet of the plant measurements could be transmitted at a time.Based on the assumption,the NCS was modeled as an asynchronous dynamical system(ADS).In the multiple-packet transmission NCS,there were also long network-induced delays,which would degrade the performance of the NCS,and could even destabilize the system.To guarantee the system's stability,Lyapunov stability theory of ADS was applied to get the sufficient conditions on the stability of the NCS with multiple-packet transmission and long time delays.The simulated experimental results show that the proposed approach is efficient.
