Bootstrap technique for Coulomb friction estimation

The bootstrap (BT) is a technique that resamples a small dataset to estimate statistical value of interest. In this paper, the BT is used to estimate the Coulomb friction force from the free decay response. Since noise and interference always exist in real data, the BT is used to capture the uncertainty of the estimated value by calculating confidence intervals. The proposed procedure is tested numerically and experimentally on testbed. As shown, it is possible to efficiently estimate the friction force on real data set.
