文摘

A fast algebraic estimation approach is proposed for multi-frequency harmonics. Amplitude, frequency and phase parameters of multiple harmonics are performed. Integral operators are used in the synthesis of the parametric estimation approach. Algebraic approach can be applied for harmonics, inter-harmonics and sub-harmonics. Analytical and numerical results confirm the algebraic estimation effectiveness.
