摘　　要：并联有源滤波器目前被广泛用于治理电网谐波污染。为保证不同用户的电能质量要求和入网电流谐波含量的规定,针对重复控制稳定性差的问题,提出适用于静止坐标系下的基于正反馈的改进重复控制策略。改进重复控制器在传统重复控制器基础上引入正反馈环节,控制器中引入零点,控制带宽和补偿增益得到提高。采用比例+改进重复控制器的复合控制器系统,对控制器进行补偿设计。Matlab仿真和试验验证了所提的改进重复控制策略谐波补偿效果良好。Shunt active power filter(SAPF)are currently widely used to control the harmonic pollution of power grid.In order to ensure the power quality requirements of different users and the lower harmonic content of the grid-connect current.Aiming at the problem of poor repetitive control stability,an improved repetitive control strategy based on positive feedback suitable for the stationary coordinate system was proposed.The improved repetitive controller introduced a positive feedback link on the basis of the traditional repetitive controller,and zero was introduced in the controller,so the control bandwidth and compensation gain were improved.The composite controller system of proportional+improved repetitive controller was used to design the compensation of the controller.Theresults of Matlab simulation and experiments verified that the improved repetitive control strategy proposed in this paperhas a good harmonic compensation effect.
