Distributed event-triggered nonfragileH∞control for networked nonlinear systems with energy constraints and redundant channels: Observer-based case

An event-triggered nonfragile distributedH(infinity)control problem is considered in this article for a class of uncertain nonlinear networked control systems over sensor networks with random communication packet dropouts and redundant channels. Redundant channel transmission is utilized to model the communication measurement and to improve the reliability and quality of the communication data transmission services. In addition, measurement size reduction technique is applied to reduce the energy consumption. An event based transmission scheme is employed to reduce the network burden and energy consumption during the data communication from the sensor to the estimator. With known conditional probability distribution, the random packet losses are modeled as a Bernoulli distributed white sequences. A new set of sufficient conditions is established by using average dwell time approach to obtain the desired observer-based distributed nonfragile controller with theH(infinity)performance requirements. Specifically, the explicit form of an observer-based feedback parameters can be obtained by solving a set of linear matrix inequalities. Finally, to demonstrate the effectiveness of the proposed observer-based feedback approach, a numerical example is exploited.
