A new method for fault detection in a free model context

This paper presents a new method of fault detection based on residual signal generation. Most the existing diagnostic methods that use to detect failure are often knowledge system model. The developed does not require precise or deep information about It is reconstruction output via an ultra-local model and model-free controller. reconstructed/estimated used build which indicator. Several simulation tests have been performed evaluate potential proposed approach for diagnosis. A actuator simulated in linear, non-linear multi-input case studies. results reveal successfully detected all these systems under noisy environment.
