Keywords: fault detection and isolation, robustness, actuator

A trend in actuator design leads to integrate the control into the unit itself so that the modern actuator includes an advanced electronic. This feature can be used to integrate fault diagnosis capabilities into the component. This paper deals with two analytical methods which allow a precise and comprehensive fault detection. The feasibility for a diagnosis tool will be proved with both methods and a comparison introduces some perspectives for the on-board application.
