摘要:相位滞后是控制系统产生振荡的一个主要原因，针对一类周期性运行系统，利用低通滤波器，提出线性相位可调的重复学习控制方法。利用指标寻优的方式对周期系统的相位偏差进行校正，补偿整体控制系统的相位滞后，并给出在数字化采样系统中的实现方法。针对单相全桥式电力逆变器，设计电压、电流双闭环控制器，将提出的可调相位超前的重复学习控制用于电压外环，以实现高精度、低谐波的交流输出电压；内环使用无滞后的电流控制器，实现快速动态响应。最后，通过MATLAB/Simulink仿真，验证了所提方法的有效性。

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.
