Abstract

In this paper, the distributed fault accommodation problem is studied for a class of interconnected nonlinear systems with event-triggered control and inter-subsystem communications. Each subsystem is subject to potential faults resulting from the local dynamics and/or transmitted from neighboring subsystems. The time periods before and after the fault detection in each subsystem are considered and corresponding event-triggered controllers are proposed, where the neural network based adaptive approximation technique is used to estimate the fault effect online. The closed-loop stability of the interconnected system with the proposed event-triggered fault accommodation controllers is rigorously analyzed.
