Abstract :
This paper presents two perturbation observers for an electropneumatic system: the first one is based on differentiation by higher order sliding mode theory, whereas the second one is based on high gain approach. The main interest of these observers is the estimation of a perturbation external force, which offers the possibility to improve the robustness of the control law. Observability analysis of a such physical system is detailed, and experimental application of both observation solutions is used in order to make a comparison between the performances of both designed observers.
