According to a class of network control system with time variable and delay, in order to decease the influence of network induceddelay on the system, this paper proposes a multiple delay model for network control system, presents the switching control strategy based on switching system theory, and analyzes the stability of the switching strategy by using Lyapunov stability criterion. Simulation results show that the multiple delay switching model can obtain good transient performance, stability performance and good realtime performance.
