Fault estimation design for dynamic systems with event-triggered sampling

摘要

This paper is preliminary concerned with fault estimation for linear time invariant dynamic system with nonuniformly sampling periods. On the basic of event-triggered scheme and full order filter, a novel filter error system is firstly designed. Furthermore, comprehensive analysis is presented to solve the parameters of the filter using LMI technique, which can keep the error system exponential stability. Finally, a drive train system of the wind turbine is given to illustrate the effectiveness of the proposed method.
