- •
The developed optimal observer is UI-decoupled and noise-attenuated.
- •
The decoupling condition supplies guidance of sensor type, rate and networking.
- •
The design of the detection threshold is adaptive.
- •
Parameter design is off-line, and the estimate update and threshold set are online.
