Abstract For the less effectiveness of conventional control methods,this paper proposes the fractional phase lead compensation repetitive control (FPLCRC) scheme.At the basis of analyzing the problems of conventional repetitive control at low sampling frequency,the principle that phase lead compensation can improve the stability of inverter is provided.The notch filter,the low pass filter,and the fractional phase lead compensator are designed,respectively to meet the requirement of the inverter stability and the steady error.Fractional phase lead compensator can be implemented by Lagrange interpolation.MATLAB/Simulink is the model and simulation platform and an inverter experimental platform is used to validate the effectiveness of the proposed control strategy.

Key words： Low sampling frequency inverter repetitive control fractional phase lead compensation Lagrange interpolation
