Dynamic Output Feedback for Nonlinear Networked Control System with System Delays and Packet Dropout

摘要

Focusing on networked control systems with state delay and packet dropout, a state feedback control for a class of nonlinear networked control systems with system delays and packet dropout is proposed. Then an observer is designed to estimate the system state. Finally, we achieve stabilization of this class of systems through a dynamic output feedback without augmentation of the state space model. From an appropriate Lyapunov-Krasovskii function, sufficient conditions which guarantee the convergence of the state variables and state estimation errors to the origin are deduced and expressed in terms of simple LMIs. Usability and simplicity are the advantages of this approach. A numerical example is given to illustrate the effectiveness of the proposed approach.
