Output feedback sampling control: a robust solution based on second order sliding mode

This paper is a first attempt for a new second order sliding mode output feedback controller. This last one is developed in the case of finite sampling frequency and is using only output information in order to ensure desired trajectory tracking with high accuracy in a finite time in spite of uncertainties and perturbations. This controller ensures the establishment of a ¿real¿ second order sliding mode behaviour and its feasibility is evaluated on an academic example.
