Abstract

A description on the methods for generating plant-friendly multisine signals is presented. Stock knowledge were used to specify a frequency band of emphasis and Fourier coefficients for the input signal, then an optimization problem was solved to determine the phases of the multisine components and the signal of Fourier coefficients to minimize plant-friendly metrics. An alternative formulation minimizes a geometric discrepancy criterion which promotes a uniform data distribution that can achieve a uniform directionality. The information content in the identification experiment was enhanced through directional sinusoids in the multisine signal, through an application of a closed-loop signal design and by minimizing an objective function based on Weyl's theorem.
