英文摘要：

The problem of quantized control of networked control systems with time-varying delay is discussed. Based on the network transmission environment,a new networked control system with delay and quantization considered is firstly modeled. Then,by using Lyapunov stability theory and linear matrix inequality（ LMI） approach,the stable condition of the system is given and the method for designing logarithmic quantization controller is proposed. Finally,simulations are implemented to demonstrate the effectiveness of the model.
