This paper studies the designment of the controller and state observer for networked control system (NCS) with bilateral random delay and packet loss. First, two groups of Bernoulli random distribution variables are introduced to describe the random delay and dropout characteristics of data packet in the forward and feedback channels, where the data packet does not have time stamps. Then, by introducing the Bernoulli random variables, the system state equation is augmented to form the new system model. Based on the Lyapunov stability theory, the sufficient conditions for the mean square exponential stability of the system are derived, and the parameters of the system observer and controller are designed by using the linear matrix inequality. Finally, the simulation results show the effectiveness of the proposed method. ? 2022, Editorial Department of the Journal of Chinese High Technology Letters. All right reserved.
