WebMar 8, 2024 · Based on the matrix mapping theory, an improved eigensystem realization algorithm (ERA), called C/ERA, is proposed in this paper. It rebuilds a Hankel matrix by replacing all elements of each anti-subdiagonal with the arithmetic average of the elements along the anti-subdiagonal, and introduces the concept of using the Frobenius norm (L2 … WebSep 24, 2024 · In this study, a reduced-order aerodynamic modeling framework by integration of a novel training data interpolation approach and the Eigensystem realization algorithm (ERA) is presented for fast prediction of transonic flutter boundary over a range of flight parameters.

Example file is provided for the identification of 2DOF system subject to gaussian white noise excitation with added uncertainty (also gaussian white noise) to both excitation and response. WebAbstract. The eigensystem realization algorithm (ERA) is a data-driven approach for subspace system identification and is widely used in many areas of engineering. … Webin practice is known as the eigensystem realization algorithm (ERA), initially pro-posed in [13], but can be found in many other sources such as [23]. ERA is a subset of a broader class of identification methods called subspace system identification, and is a purely data-driven approach consisting of two main steps.
