Harmonic detect based on BP network and Fourier progression

A harmonic detect method based on BP network is introduced. BP output in Fourier format equals with Fourier progression, so BP network is designed to be a SISI system. Hidden layer is composed with Fourier trigonometric function as activation function. Gradient descent regulates weight to reduce error. To insure the convergence of the BP network, learning step η is settled according the Lyapunov theorem. Simulation result shows that it can acquire harmonics magnitude and phrase precisely and quickly.
