Quantitative analysis of incipient fault detectability for time-varying stochastic systems based on weighted moving average approach

作者：

Highlights：

• Fault detectability is defined for stochastic systems by considering FAR and MDR.

• Detectability of incipient faults is quantitatively analyzed by using statistical theory.

• A novel incipient fault detection method is designed for stochastic systems.
