Harmonic Current Detecting Method Based on Improved SVSLMS

This paper presents an improved SVSLMS (Sigmoid Variable Step-size Least Mean Square) harmonic current detecting method based on the analysis of the steady-state error generated by traditional SVSLMS. This method redefines and selects the feedback error coefficient. By using a frequency-selective fi...

Description
Summary:This paper presents an improved SVSLMS (Sigmoid Variable Step-size Least Mean Square) harmonic current detecting method based on the analysis of the steady-state error generated by traditional SVSLMS. This method redefines and selects the feedback error coefficient. By using a frequency-selective filter for filtering the original feedback error, it reduces the effects of harmonics on detection performance, further improves the response speed and steady precision. Simulation results verify the effectiveness and practicality of this method.
