为解决应用于LCL型并网逆变器的传统反步控制策略所存在的计算量大、测量噪声被成倍放大的问题，提出一种基于加权平均电流控制WACC（weighted average current control）的改进反步控制策略。首先，利用WACC策略将LCL三阶滤波系统降阶为一阶，在有效减少整体计算量的同时，降低对虚拟控制量的求导次数；然后，利用滑模观测器对加权平均电流进行观测，以减小LCL滤波器参数摄动对加权平均电流精度的影响；最后，依据所建立的等效系统模型设计反步控制器，控制并网电流。仿真与实验结果表明，所提控制策略具有良好的稳态性能和较高的鲁棒性。

To solve the problems of computational complexity and exponential amplification of measurement noise under the traditional backstepping control strategy applied to an LCL grid-connected inverter, an improved backstepping control strategy based on weighted average current control (WACC) is proposed in this paper. First, the order of the LCL filtering system is reduced from third-order to first-order by means of the WACC strategy, which effectively alleviates the overall computation load and decreases the number of derivations required for virtual control quantities. Then, a sliding-mode observer is utilized to observe the weighted average current, so as to lessen the influence of LCL filter parameter perturbation on the accuracy of weighted average current. Finally, a backstepping controller is designed to regulate the grid-connected current based on the established equivalent system model. Simulation and experimental results prove that the proposed control strategy has a good steady-state performance and high robustness.
