Abstract：The exponential stability problem is studied for the networked control systems with bilateral time-varying delay of sensor-to-controller and controller-to-actuator. A discrete-time switched closed-loop system with uncertain pa-rameters is modeled by partitioning the range of time-varying delay into multi-equal intervals and using the method of augmented matrix. Then the condition meeting the exponential stability in the closed-loop system is presented, and the quantitative relation between the number of delay intervals and the exponential decay rate is established based on the ap-proach of average dwell time. The proposed design method can decrease the conservatism of the system design and shorten the convergence time to some degree. Finally, the simulation results are given to illustrate the effectiveness of the proposed method.
