摘要：A method for establishing a simulating signal suitable for estimating a complex

exponential signal includes the following computer-implemented steps: sampling a timedomain signal of a physical system to obtain a sampling signal; transforming the samplingsignal to a frequency domain signal using Fast Fourier Transform; determining

parameters of the frequency domain signal; establishing a simulating signal; establishinga target function which is a deviation of the simulating signal from the sampling signal;obtaining correcting factors; iterating the target function using a gradient method andthe correcting factors to obtain three sets of iterated signal parameters; obtainingcorrected parameters using quadratic interpolation; and using the corrected parametersto correct the simulating signal, and establishing an updated target function. Thesimulating signal can be used to estimate dynamic behavior of the physical system if theupdated target function converges to a tolerable range.
