Lesson 9-I: Exponential Model Fitting with Excel – MA 132
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 ... WebUse non-linear least squares to fit a function, f, to data. Assumes ydata = f (xdata, *params) + eps. Parameters: fcallable The model function, f (x, …). It must take the independent variable as the first argument and the parameters to fit as separate remaining arguments. xdataarray_like The independent variable where the data is measured.
