Abstract [en]

The problem of first order differentiation, when an estimation of an upper bound of the second derivative is available on-line, is studied in this paper. The proposed method include two approaches: Second Order Sliding Mode and High-Gain algorithms, and consider the differentiator gain as a continuous time varying function. This scheme provides chattering attenuation, increasing at the same time the overall performance. Experimental results, realized over an Industrial Hydraulic System, confirm the efficiency of the methodology.
