摘　　要：基于内模控制器(IMC)的原理,提出了一种新的可跟踪交流信号无静差的二阶IMC。该控制器可直接控制交流电流,避免了选择坐标变换和解耦算法,且具有较高的鲁棒性。在此以三相并网逆变器为研究对象,对其二阶IMC结构和参数进行了设计,并搭建了仿真和实验平台进行验证。仿真结果验证了二阶IMC的鲁棒性,实验结果验证了其有效性和稳定性。Based on the principle of internal model controller（IMC ）, this paper presents a novel second-order IMC which can tract AC signal without static error and this kind of controller is more robust.The coordinating transfer and decoupling can be omitted by adopting this control strategy.Design procedure of the second-order IMC＇s structure and parameters are given.Simulation and experimental platforms are built for the controller.The simulation results prove the robustness of the controller and the experimental results prove the validity and stability of this controller.
