Experimental data from " A two-harmonic homotopy method to experimentally uncover isolated resonances"

Original publicationRaze, G. & Kerschen, G. A two-harmonic homotopy method to experimentally uncover isolated resonancesAbstractSecondary resonances of nonlinear systems can appear as isolated branches of solutions, challenging their characterization and making them particularly difficult to observe experimentally. This work exploits a two-harmonic homotopy method that leverages two-harmonic forcing as a proxy to connect primary and secondary resonances. An experimental implementation with simple feedback controllers is presented. This approach is then validated with an electronic Duffing oscillator and a doubly clamped beam featuring a distributed geometrical nonlinearity. It is shown to experimentally uncover isolas in both these examples.Description of the datasetThis dataset contains all experimental data necessary to plot the figures of the aforementioned journal article, displaying results of various tests on an electronic Duffing oscillator, and a doubly-clamped beam. Data was acquired with a MicroLabBox from dSPACE.UseThe figures can be plotted with Matlab scripts. Please refer to the file readme.m for more information.
