Abstract

Modeling of systems in engineering involves two major stages. First, a system structure is derived that is based on the fundamental laws from physics that characterize the relevant processes. Second, specific parameter values are determined by minimizing the distance between the measured and simulated system outputs. In previous work, strategies for verified parameter identification using techniques from interval analysis were developed. These techniques are extended in this paper to a verified estimation for systems with non-smooth ordinary differential equations. Suitable experimental results for parameter estimation of a mechanical system with friction conclude this contribution to highlight the practical applicability of the developed identification procedure.
