This paper studies a class of quantitative control problem for networked systems with time-delay distributed dependence.Firstly, under the influence of signal quantization, a new networked system model is constructed, which includes the probability distribution information and signal quantization information of delay interval. Lyapunov stability theory, convexity of matrix function, free weights and Jessen inequality, the asymptotic stability and the stability of the system are given. Finally, the linear matrix inequality (LMI) technique is used to solve the quantitative controller. The simulation results and horizontal The comparison results verify the effectiveness of the proposed method.
