This paper considers the problem of quantized control for a class of networked control system(NCS). The new
model of NCS are derived considering the delay, packet dropout, quantization and delay probability distribution. Then by
using of the analysis method of Lyapunov stability theory, convexity of matix function, free-weighting technology and Jessen
inequalities etc, the stability and stabilization criteria are given. Quantized controller is designed by using of LMI technology.
Finally, the results of the simulation and the comparation with related paper show the effectiveness of the proposed method.
