This paper investigates the problem of networked finite-frequency fault detection triggered by event-triggered communication mechanism. Under the event-triggered communication mechanism, the networked finite-frequency fault detection system is modeled as a bimodal switched linear system. According to the finite-frequency inequal- Finite-frequency input.With Finlser’s lemma and finite-frequency input characteristics, a joint design algorithm of fault observer and transmission mechanism under high frequency disturbance and low-frequency fault input is given.Finally, numerical examples are given to illustrate the effectiveness of the proposed method Sex.
