Phase Space Reconstruction and Approximating Relative Degree from Input-Output Time Series Data
Walker, David M.; Tufillaro, Nicholas B.
Keyword(s): phase space; relative degree; nonlinear time series
Abstract: In this report we attempt to calculate values of important quantities in nonlinear control theory directly from input-output time series data. Straightforward attempts to numerically calculate the "relative degree" of a nonlinear control system fail to produce reliable estimates.
