- •
A novel method for fault detection of complex structures using an optimized virtual beam-like structure approach.
- •
A ‘virtual beam’ consists of a sensor chain automatically obtained by an Improved Bacterial Optimization Algorithm from the sensor network.
- •
The method needs less or little prior knowledge of the faults, does not require stationary response data, and is not applicable only to a specific structure.
- •
The proposed fault diagnosis method is extensively tested in a real satellite-like model.
