  • Method and framework for system identification using only pre-bifurcation data
    Patent number: 11604851
    Abstract: Frameworks and methods for generating early-warning indicators of impending nonlinear instabilities of a dynamical system are provided. In accordance with one aspect, the framework includes a data collector and a system identification (SI) modeler. The data collector is coupled to the dynamical system and collects pre-bifurcation data. The SI modeler predicts early-warning indicators of impending nonlinear instabilities using only the pre-bifurcation data and the SI modeler includes a means for extrapolating Fokker-Planck coefficients in response to the pre-bifurcation data to generate precursors to a Hopf bifurcation and/or to identify a type of the Hopf bifurcation and/or to forecast the limit-cycle oscillation (LCO) amplitudes of a post-bifurcation regime. In addition, the SI modeler predicts the locations of the Hopf bifurcation points, the type of the Hopf bifurcation and the LCO amplitudes of the post-bifurcation regime.
