On the Uncertainty Analysis via Low Frequency Inputs for Hydraulic Cylinder Dynamics

This paper discusses a new uncertainty analysis via low frequency inputs for hydraulic cylinder dynamics. First, we review the nonlinear nominal modeling and existence of nonlinearity phenomenon despite absence friction. Second, propose by both physical parameter identification measurement input-output behavior input within domain. Finally, experimentally apply without ignoring region. Unexpectedly, there is non-negligible domain which can be important model-based control robots.
