| Abstract: | This paper analyzes stability of networked linear systems（ NCS） with random communication delays in bidirectional communication channels. The random communication delay is modeled as a Bernoulli random binary distribution. Sufficient conditions for a closed-loop networked linear system are globally exponentially stable according to the Lyapunov stability theory. The observer-based controller can easily be solved with linear matrix inequality（ LMI） solvers. Effectiveness of the proposed method is verified with a numerical example. |
