摘要
This article concerns with the dynamic event-triggered fault interval estimation and accommodation for aeroengine sensors. First, a dynamic event-triggered based robust augmented state observer is designed to reconstruct sensor fault for an aeroengine subject to external disturbance and measurement noise. Next, the event-triggered parameters and fault-tolerant controller are codesigned based on the obtained observer gains to save communication resources. Moreover, the interval estimation of the sensor fault is achieved via reachability analysis. Eventually, the designed scheme is tested with aeroengine Hardware-in-the-loop experiment, which illustrates its potential in aeronautical engineering.
