Event-triggered fault detection — An integrated design approach directly toward fault diagnosis performance

Dear Editor, This letter investigates an integrated design approach directly toward fault diagnosis performance for event-triggered systems. By evaluating the effects of all external inputs on residual under the event-triggered mechanism, the event-triggered false alarm rate (FAR) and fault detection rate (FDR) are defined and their relationship is established. Based on this, the residual generation and evaluation are designed in an integrated manner to maximize temp FDR for a given FAR with the help of linear matrix inequality (LMI) and an iterative algorithm. A benchmark model of vehicle lateral dynamics system is employed to demonstrate the superiority of the proposed approach over the existing widely used separated design approaches.
