Event-Triggered fault detection, isolation and control design of linear systems

Abstract

In this paper, the problem of event-Triggered integrated fault detection, isolation and control (E-IFDIC) for discrete-Time linear systems is considered. Using a filter to represent, characterize, and specify the E-IFDIC module, a multi-objective formulation of the problem is presented based on the H /H performance criterion. It is shown that by using an event-Triggered technique applied to both the sensor and filter nodes, the amount of data that is sent through the sensor-To-filter and filter-To-Actuator channels are dramatically decreased. A set of linear matrix inequality (LMI) feasibility conditions are derived to ensure the solvability of the problem as well as to simultaneously obtain the filter parameters and the event-Triggered conditions. A numerical example is also provided to illustrate the effectiveness of our proposed design methodology. 2015 IEEE.
