Discovering governing equations from data by sparse identification of nonlinear dynamical systems.
Extracting governing equations from data is a central challenge in many diverse areas of science and engineering. Data are abundant whereas models often remain elusive, as in climate science, neuroscience, ecology, finance, and epidemiology, to name only a few examples. In this work, we combine sparsity-promoting techniques and machine learning with nonlinear dynamical systems to discover gover...
متن کاملDiscovering governing equations from data: Sparse identification of nonlinear dynamical systems
The ability to discover physical laws and governing equations from data is one of humankind’s greatest intellectual achievements. A quantitative understanding of dynamic constraints and balances in nature has facilitated rapid development of knowledge and enabled advanced technological achievements, including aircraft, combustion engines, satellites, and electrical power. In this work, we combi...
متن کاملFinite time stabilization of time-delay nonlinear systems with uncertainty and time-varying delay
In this paper, the problem of finite-time stability and finite-time stabilization for a specific class of dynamical systems with nonlinear functions in the presence time-varying delay and norm-bounded uncertainty terms is investigated. Nonlinear functions are considered to satisfy the Lipchitz conditions. At first, sufficient conditions to guarantee the finite-time stability for time-delay nonl...
متن کاملInstantaneous Characterization of Time-varying Nonlinear Systems Instantaneous Characterization of Time-varying Nonlinear Systems
A nonlinear system may be characterized by an orthogonal functional power series (FPS) computed from cross correlations between input and output variables. \Is the response changing over the course of the experiment?" is a fundamental question encountered in the analysis of both FPS and evoked potentials (EP's). Regression on closed-form functions of time produces a time-varying FPS or EP. Eval...
متن کاملIdentification of Time Varying Systems
The article outlines the development of time variable parameter (TVP) estimation as an approach to modeling nonstationary dynamic systems. It then describes one of the latest methods for estimating time variable parameters in dynamic auto-regressive, exogenous variables (DARX) and dynamic transfer function (DTF) models. In the case of DARX models, the estimation methodology is based on standard...
