摘　　要：设计一种具有零稳态误差的单相并网逆变器系统。详细的讨论分析了比例积分(PI)控制器、比例谐振(PR)控制器和准比例谐振(PR)控制器。利用MATLAB/Simulink搭建单相并网逆变器仿真模型并进行仿真分析,证明了准PR控制器消除稳态误差和抗电网干扰方面的优越性。最后,搭建了一个1k W的基于准比例谐振控制的单相并网逆变器实验装置,对理论分析结果进行了验证。A novel grid-connected inverter system with zero steady-state error is developed in this paper. The control principles of PI control, PR control and quasi-PR grid-connected inverter system is built, simulated the single phase gird connected inverter achieves ty. Finally, it built a 1 kW grid-connected inverter verified by exoeriments. control were well specified in this paper. The simulative model of the and analyzed in MATLAB/SIMULINK. By using quasi-PR controller, both zero-steady-state error and the good disturbance rejection capabili- system based on quasi-PR control and the theoretical analysis has been
