New Stability Criteria of Networked Control Systems

We present new stability criteria for networked control systems with time-varying transmission delays and transmission intervals.The accumulating transmission delays are described as potential input delays.Also,the impulsive effects of the networked control system are analyzed in detail.We propose a new discontinuous Lyapunov functional method to exploit the impulsive effects of feedback signals and input delays and their associated time derivatives;this method leads to reduced conservatism of the derived exponential stability criteria and the corresponding controller design method.A numerical example is presented to verify the effectiveness of our proposed approach.
