| Abstract: | An optimal event-triggered fault detection method based on diagnostic observer is proposed. Firstly, a low-order diagnostic observer parameter matrix calculation method combining a numerical approach and an algebraic approach is developed to satisfy Luenberger conditions in residual generation for the remote monitoring system which is triggered by adaptive mixed event-triggered mechanism. Then, the $H_{infty |
