摘　　要：首先采用解析逆系统理论对模型电流动态环节的可逆性进行了分析,推导出解析逆系统,消除了电流分量之间的耦合,从而实现电流环的高动、静态性能控制。然后设计了直流母线电压调节器,提出了基于电流解析逆控制的光伏并网逆变发电系统结构。最后,采用Matlab/Aimulink对整个系统进行仿真研究,验证了所提系统结构的有效性。The model of PV grid connected inverter generation system under synchronous rotating coordinate frame （dq） is three order, multivariate and couple nonlinear system, in this paper, the invertibility of the current dynamic system was analyzed firstly, the analytic inverse system was deduced, and the coupling between the two current components was cancelled, which make easy to realize the high static and dynamic performance control. And then the DC link voltage regulator was designed, the PV grid connected inverter generation system structure based on current analytic inverse control was proposed. At last, the simulation study of the system was done with the Matlab/Simulink, the performance of the proposed system was verified.
