Abstract: The phase delay is a main reason resulting in the oscillation of control system． For a class of periodic system，a repetitive learning control method with adjustable linear phase was proposed by using a low-pass filter． The phase delay of whole system was searched by using a method of optimized target，and was adjusted and compensated． An implementation approach of the proposed algorithm was deduced for a digital sampled system． Voltage and current dual closed-loop controller was designed for single phase full bridge power system，in which the proposed phase-lead repetitive learning controller was applied at the outer voltage loop to implement higher precision and lower harmonic output voltage． At inner loop，a current controller was equipped without delay to achieve a fast dynamic response． Finally，the validity of the proposed method was verified by MATLAB /Simulink platform.
