With the development of network technology,Ethernet has been gradually introduced into industrial control fields.Because of the ineluctability of the network-induced time delay and data packet dropout,model creation for NCSs must take them into account especially.The article analyses the character of the network-induced time delay and establishes a Model based on Data packet dropout into Asynchronous Dynamical Systems,then simulinks the NCSs with PID method.Aiming at network-induced time delay and data packet dropout of NCS,the article analyses the stability of the NCS and testifies the proper range of Data packet dropout for keeping the system stable.
