Robust stabilization of uncertain nonlinear networked control systems with packet dropouts and quantization

Abstract

In this paper, the robust stabilization problem of uncertain networked control systems subject to packet dropouts and signal quantization. Random data packet dropouts in the channels are modeled as independent Bernoulli processes. Quantized signal measurement is handled by a sector-bound method, in which the quantization error is treated as sector-bounded uncertainty. Based on Lyapunov theory, a static feedback controller is obtained in terms of linear matrix inequality (LMI) to ensure the asymptotically stability of the closed-loop system. At last, a numerical simulation example is used to show the validity of the designed controller.
