This paper discusses about the modeling and stability of a class of multiple time-delay and multi-variable net
control system(NCS). Firstly, by supposing that sensor nodes are time driven, and controller and actuators are event driven,
an MIMO model in time domain is provided for the system. Then a Lyapunov function is built based on Lyapunov stability
theory and Razumikhin theory, and its stability and the conditions of delay parameter and stability are obtained. Finally,
simulation example shows the criterion about the NCS.
