Controller Design for Nonlinear Networked Control Systems with Random Data Packet Dropout

AbstractThis paper investigates the state feedback control problem of nonlinear networked control systems in presence of data packet dropout. The random data packet dropout is modeled as a Bernoulli distributed sequence with a known conditional probability distribution. The closed-loop system model is obtained through the state augmentation method. The sufficient conditions for the existence of a state feedback controller are derived by means of Lyapunov stability theory such that the closed-loop control system is exponentially stable in the mean-square sense. The maximum bound of the nonlinear item of the control system is also obtained. Then a linear matrix inequality (LMI) based approach for designing such a controller which can be solved by Matlab LMI tool box is presented. Finally, a numerical simulation example is used to demonstrate the effectiveness of the proposed method.

KeywordsData Packet Dropout, Exponentially Mean-square Stable, Linear Matrix Inequality, Nonlinear.
