WebIn this paper, a DFT-based method with an exponential window function is proposed to identify oscillation modes from each segment of transient data in PMUs. This window function allows the application of the least squares method (LSM) for modal identification in the same manner as the conventional method. ... Such curve-fitting is performed on ... WebSep 9, 2024 · it searches for the logarithm of α: y ( t) ∼ y f + ( y 0 − y f) e − exp ( log α) t. From the fit result, you can plot the fitted curve, or extract whichever information you need: qplot (t, y, data = augment(fit)) + geom_line(aes(y = .fitted)) For a single curve, it’s easy to guess the approximate fit parameters by looking at the plot ...
