摘　　要：针对传统控制器动态性能差、稳态跟踪精度不高、无法对变化的谐波电流进行实时调整的问题,提出一种基于LCL型有源电力滤波器的并联型复合电流控制策略。将模糊PI控制器和快速重复控制器结合,提高了系统的动态响应速度和稳态补偿精度,并给出了详细的设计方案。为了提高直流侧电容的稳压速度,对电容电压控制设计了模糊PI控制。最后仿真验证了该控制策略的有效性和优越性。The traditional controller has poor dynamic performance and low steady-state tracking accuracy,which cannot adjust the harmonic current in real time.In this paper,a shunt compound current control strategy based on an LCL active power filter is proposed.The fuzzy PI controller is combined with the fast repetition controller to improve the dynamic response speed and steady-state compensation accuracy of the system.The detailed design scheme is also given.In order to improve the voltage regulation speed of the dc-side capacitor,fuzzy PI control is designed for capacitor voltage control.Finally,the effectiveness and superiority of the proposed control strategy are verified by simulation.
