Ultimately Bounded Output Feedback Control for Networked Nonlinear Systems With Unreliable Communication Channel:A Buffer-Aided Strategy
This paper concerns ultimately bounded output-feedback control problems for networked systems with unknown nonlinear dynamics.Sensor-to-observer signal transmission is facilitated over networks that has communication constraints.These transmissions are carried out over an unreliable communi-cation channel.In order to enhance the utilization rate of mea-surement data,a buffer-aided strategy is novelly employed to store historical measurements when communication networks are inaccessible.Using the neural network technique,a novel observer-based controller is introduced to address effects of sig-nal transmission behaviors and unknown nonlinear dynamics.Through the application of stochastic analysis and Lyapunov sta-bility,a joint framework is constructed for analyzing resultant system performance under the introduced controller.Subse-quently,existence conditions for the desired output-feedback con-troller are delineated.The required parameters for the observer-based controller are then determined by resolving some specific matrix inequalities.Finally,a simulation example is showcased to confirm method efficacy.
